Abstract :
The design of a second-order low-pass IIR filter based on time-mode signal processing circuits is presented. The filter is implemented using a set of building blocks that perform basic mathematical operations in the time-domain including time addition, weighted delayed time addition and subtraction, and unit delay. A second-order low-pass Chebyshev filter was designed in a 0.18 mum CMOS process. Simulation results confirmed that the design can achieve low-pass filtering, providing a maximum SNR of 63.6 dB and SNDR of 44.1 dB.
