Latest Patents

Younghyun Lim holds a patent for a "Ring oscillator based frequency divider." This invention relates to a ring oscillator (RO) frequency divider that is designed to frequency divide an input clock by a programmable divider ratio to generate an output clock. The RO frequency divider receives the input clock and enables each of a ring of N cascaded inverter stages substantially one at a time in response to the input clock. It outputs a second clock from an output of one of the ring of N cascaded inverter stages. Each stage of the divider includes a p-channel metal oxide semiconductor field effect transistor (PMOS FET) coupled in series with an n-channel metal oxide semiconductor field effect transistor (NMOS FET). In another configuration, each stage includes two PMOS FETs and an NMOS FET. This innovative approach allows for greater flexibility and efficiency in clock signal management.
