Burst-pulse Generator based on transmission line toward sub-MMW

A Transmission-line-based Burst-pulse Generator (TPG) is proposed in this paper. The proposed architecture does not consume power in standby stage, so it is more suitable in a pulse system than a continuous wave generator. Also, the center frequency of the pulse can be higher than the F
max
of a CMOS process, since the pulse oscillation need not be sustained. The architecture is modeled and simulated in a 0.18-µm CMOS process, then the performance is compared with a push-push oscillator, which is a conventional method to generate frequency higher than process's F
max
. It is shown that our TPG has better energy conversion efficiency up to a pulse duty cycle of 10%, and the oscillation frequency above 2F
max
of the process is achieved.
