Abstract

In this paper, we discuss linear power amplifier and RC polyphase filter design in 90 nm CMOS process which dominate QoS in high throughput wireless communication system. From the theoretical analysis, we show that only class A operation can be a linear power amplifier and its maximum drain efficiency reaches 67[%] in CMOS process. We also propose an RC polyphase filter (PPF) design using frequency transformation from the prototype LPF and evaluate its parasitic effect. Both power amplifier and RC PPF are fabricated using TSMC 90 nm process.
