Abstract
A ring-based multi-push voltage-controlled oscillator (VCO) generates a multi-push output signal using a control voltage. The ring-based multi-push VCO includes a plurality of delay cells, a plurality of buffer amplifiers, and a bias unit. The delay cells connect each other in sequence to form a ring structure, and each delay cell connects with the respective buffer amplifier. The bias unit connects with the buffer amplifiers to output the multi-push output signal. The control voltage supplied to the delay cells is utilized to control the frequency of the multi-push output signal, and the ring structure formed by the delay cells is to multiply the frequency of the multi-push output signal to increase the frequency tuning range.
