Theused for dielectric phase shifter must have a large relative dielectric constant, strong dielectric ity, small dielectric loss and low leakage current. In this paper, some works were done to optimize the properties of thin films, including the annealing temperature, orientation and composition gradient. thin films were prepared by rf-magnetron sputtering system. And Effects of O2/Ar and Zr/Ti on the properties thin films were investigated. At last, the temperature character and fatigue of , BZT thin films were tested. The following results are obtained:1. BZT thin films deposited on the different substrates can bear the different annealing temperature （900℃-Al2O3 substrate, 1100℃-LaAlO3 substrate, 1200℃-MgO substrate）. The substrate lattice constants and thermal expansion coefficients are the main factors to influence the annealing temperature. High temperature is good for the dielectric ity of BST films.2. （110）-oriented BST has stronger ferroelectric properties than （100）-oriented BST thin films. （110）-oriented BST with smaller tgδhas larger relative dielectric constant and tunability.3. BST thin films with composition gradient have lower tunability and dielectric loss than single-layer structure. Ba0.5Sr0.5TiO3/Ba0.6Sr0.4TiO3 have better properties than Ba0.6Sr0.4 TiO3/Ba0.5Sr0.5TiO3.4. BZT thin films were prepared by rf-magnetron sputtering. BZT thin films are crystallized, no pinholes, dense and uniform. BZT thin films have slim hysteresis loop and low leakage current. When E=400kV/cm, the tunability is 15%, tgδis 0.016. After halving thickness （E=800kV/cm）, the tunability is increased to 33.5%, tgδis 0.021.5. With the increase of O2/Ar, the preferred orientation of BZT thin films changes from （l00） to （111） direction. The grain size, RMS, relative dielectric constant and tunability become larger with the increase of the O2/Ar ratio. The ferroelectric properties also have been enhanced. 6. Compared BaZr0.1Ti0.9O3 to BaZr0.2Ti0.8O3, it is found that the ferroelectric properties, relative dielectric constant and the tunability increase with reducing the Zr4+. The tunability is increased to 60.5% when E=800kV/cm.7. From -30℃to 130℃, the relative dielectric constant of BST and BZT thin films increase slowly with the temperature. There is no Curie point in this temperature rang. From -50℃to 150℃, the curves are relatively flat at 1MHz. It is also found that the dielectric ity of BST, BZT thin films is difficult to fatigue.
The powerIC (integrated circuit) has the many advantages, such as high integrity, high price ratio, the most simple outer circle circuit, the best capability, the high-efficiency power supply etc. So it has the vast market demand. This paper aims to the application that requires high and low noise. Under this context a high and low noise (low dropout regulator) is designed.In the , reference is a critical circuitry that it determines the accuracy. Using Curvature-Compensation, the temperature coefficient is greatly improved, from about 20ppm/℃to 0.5ppm/℃.A preregulator help to higher the PSRR (power supply rejection ratio) and a 500nF off-chip capacitor bypasses most of the reference’s output referred noise.This paper takes advantage of the 0.5μm BiCMOS process that the bipolar transistor has lower flicker noise than their MOS counterparts, so bipolar transistor is used to form the critical node of the error amplifier. To make sure the stability and lower the transient overshoot of the , a buffer stage is used to isolate the pass element and the output of the error amplifier. The output resistance of the buffer is reduced by a negative feedback. And the buffer is dynamically biased to reduce quiescent current of the LDO. Two zeros are introduced near the non-dominate poles as the frequency compensation.This paper first shows the prospective market demand of power IC, then it introduce the specifications of the LDO. In the next, some relative analyze is performed and noise analyze is performed. After this, a reference is designed and then the other parts of the LDO. Simulation is performed under the Cadence Spectre environment, and the results show that all specifications are achieved.
With the rapid development of microwave technology,the demands for microwave passive components,such as filters and,used in microwave communications,microwave navigation,remote control,satellite communications and military countermeasures are increasing.Because of increasing radio communications users,the frequency resources become increasingly stringent.The frequency space assigned to the various types of communication systems becomes more and more dense.In order to cope with the increasing demand for capacity in restricted spectral bandwidths,filter structure tends to use the form of which is based on the general Chebyshev functionf.The interposition of between cavities can lead a transmission zero,so to increase the steepness of cut-off frequency and enhance the superiority of filters.The use of filter can reduce the filter order,the insertion loss and band distortion.Comparing with the direct coupling filter of the same suppression,the corss-coupling filter has a good implementation of filter miniaturization.Directional coupler as an important component in microwave systems have a wide range of applications,such as mixers,amplifiers,modulators and an antenna system to merge or separate the phase othogonal signals,or to extract monitor signal for monitoring circuit.However,there are many defects in the production by using the traditional parallel-coupled line to realize the strong coupling.In this paper,it is presented a new type of sublayer-type coupling structure parallel line to break through the limitations of manufacturing process.This new structure is realized by adding the underlay conductor under the edge-coupled stripline and paralleling with it for same length.The design and fabrication method of a 6-dB coupler worked in ultra-wide band from 0.35GHz to 3.8GHz have been stated in detail.The coupler has 5 sections comprising two sections of using underlay structure and three sections of using conventional stripline.The capacitive open-line is loaded to the coupler with discontinuity of striplines for compensating circuit.This method can improve the circuit’s match performance and reduce the component’s return loss.Filter design is based on Chebyshev filter synthesis,and focuses on the miniaturization of cross-coupling filter by synthesizing with network forms and step-impedance resonator.After systematicly discussing the fundamental characteristics of step-impedance resonator.An analysis of the generalized Chebyshev transfer function and synthesization of prototype network corresponding to both of symmetric and asymmetric distributions then follow.A filter with center frequency of 2GHz and bandwidth of 50MHz is designed in the cross-coupling case.The experiment result shows the feasibility of the design.The design reduces the filter volume by 30%.
