Latest Patents

One of Wonjoo Jung's latest patents is a quadrature error correction circuit and semiconductor memory device that includes this innovative circuit. The quadrature error correction circuit comprises a duty cycle adjusting circuit, a phase interpolator, a phase detector, and a delay control circuit. The duty cycle adjusting circuit generates a first corrected clock signal and a second corrected clock signal, which have their skew and duty cycle errors concurrently adjusted. This adjustment is achieved by modifying the delay of the edges of a second clock signal and the falling edge of a first clock signal based on first through fourth control code sets. The phase interpolator generates a second delayed and selected clock signal by delaying a second selected clock signal chosen from the first through fourth adjusted clock signals. Additionally, the phase detector detects the phase difference between a first selected clock signal and the second delayed and selected clock signal to produce an up/down signal. The delay control circuit then generates the first through fourth control code sets based on this up/down signal.
