This paper presents an approach to design of a high frequency switched capacitor filters for video communication networks. In the case of low OSR, using common methods reduces the SNDR and accuracy of the filter. Bilinear implementation techniques are applied to an untried fifth-order elliptic SC filter, and are simulated in a 0.35mm CMOS technology. Cutoff(More)
In this work, an integrated Doherty power amplifier in 0.18 im CMOS process is presented for WiMax applications at 2.5 GHz. Doherty configuration with cascode structure is adopted to achieve high efficiency and output power. The scaling and transistor size of main and peaking amplifier is iteratively determined to result optimum power splitting between main(More)
In this work a novel and efficient approach is used to optimize linearity and efficiency of power amplifier used in mobile WiMAX application. A linear and high performance push amplifier is designed and implemented in 0.18 im CMOS technology to enhance linearity of class E switched mode power amplifier. Proposed push amplifier has two section; analog and(More)
