Abstract
A high-speed DCO is proposed that uses the negative-skewed delay scheme. The DCO consists of a ring of inverters with each PMOS transistor driven from the output of 3 earlier stage through a set of minimum-sized pass-transistors. The digitization of negative-skewed delay is achieved by selecting pass-transistors turned on and digitizing the gate voltages of the selected pass-transistors. The proposed 7-stage DCO has been simulated using 1.8V,
