Summary: 
A finite impulse response (FIR) core based on the cascoded class AB SI technique is presented for low power wireless transceivers. Accomplished through both architectural and circuit developments, the filter's features include high speed, low power consumption, small silicon area and compatibility with standard CMOS process. For feasibility and performance assessments, an 8-tap 16 MS/s SI FIR filter with 5-bit coefficients and a 31-tap 80 MS/s SI matched filter (MF) for despreading task in future WCDMA receivers are demonstrated via simulations.
