A 0.8-1.2GHz Single-Phase Resonant-Clocked FIR Filter with Level-Sensitive Latches

In this paper, we present the design and experimental validation of RF1, a 0.8-1.2GHz frequency-scalable, resonant-clocked FIR filter test-chip with level-sensitive latches. Designed using a fully automated ASIC flow, RF1 was fabricated in a 0.13mum CMOS process with an on-chip inductor and clock generator. At its resonant frequency of 1.03GHz, RF1 dissipates 132mW, with clock power accounting for only 10.8% of total power dissipation. Resonating 42pF of clock load, RF1 achieves 76% clock-power efficiency over CV² f.
