This paper presents a pulse generator (PG), aiming at low power applications with low duty cycle. The PG is capable to provide an efficient pulse generation at a frequency near and beyond CMOS’s Fmax. It also features quick starting time and zero stand-by power. The PG is designed by CMOS flipped to a transmission line resonator on a quartz substrate. Efficiency, oscillation frequency and pulse duration can be tuned by adjusting the transmission line parameters. Two prototypes with coupling gap of 1μm and 2μm at 11.5GHz oscillation frequency are fabricated. Measurement shows energy conversion efficiency of 2.37% and 2.05%, respectively, with energy consumption of 5.4pJ/ pulse.
