Abstract :
A two-tap infinite impulse response (IIR) filter using travelling-wave architecture is presented. The filter utilises poles as a means of frequency boosting, contrasting the conventional finite impulse response technique of utilising zeros and is the first ever implementation of an IIR filter using a double-loop multi-delay topology. Implemented in a 90 nm CMOS process, the filter achieves a 12.1 peak at 24 GHz when both filter taps are set to maximum peaking and consumes 55.2 mW from a 1.2 V supply.
