Latest Patents
Cho's latest patents include "Differential current mode low latency modulation and demodulation for chip-to-chip connection." This invention presents a chip-to-chip communications circuit that is particularly well-suited for short-range communication, typically less than a few inches, between integrated circuits. The circuit utilizes multi-frequency quadrature amplitude modulation (QAM) mechanisms to convert digital data bits from a parallel form into a serial analog stream for communication over a chip I/O connection. The use of differential current mode modulation in the transmitter and demodulation in the receiver reduces latency and power consumption while increasing manufacturing yields and resilience to process variations.
Another notable patent is "Phase synchronization of modulation or demodulation for QAM-based multiband TSV-link." This invention also focuses on short-range wired RF communication between integrated circuits. It employs multi-frequency quadrature amplitude modulation (QAM) mechanisms for data conversion. During a phase calibration cycle, a phase adjustment controller in the transmitter works with a phase adjustment controller in the receiver to adjust a phase locked-loop (PLL) circuit, correcting for phase delays that occur due to signal propagation.
