Title: Innovations of Ricky Y Chen
Introduction
Ricky Y Chen is a notable inventor based in Irvine, California, recognized for his contributions to the field of transceiver technology. With a total of three patents to his name, Chen has made significant advancements that enhance the performance and efficiency of communication systems.
Latest Patents
One of Chen's latest patents is for a self-calibrating, self-correcting transceiver and methods. This innovative transceiver incorporates a digital signal processor that can insert calibration signals of known levels and frequencies into transmitters. This process allows for the calibration and correction of transmitter parameters, ensuring optimal performance. The output from the calibrated transmitter is then coupled into a calibration mixer, along with a mixing signal from a local oscillator generator, facilitating further calibration of receiver parameters.
Another significant patent by Chen is the differential pair gain control stage. This invention features a gain control differential pair (GCDP) that conducts current in response to a differential drive signal. The gain of the signal path is controlled by the drive signal, which helps reduce noise caused by the GCDP. This technology is particularly beneficial when implemented as part of a Gilbert mixer, as it regulates the RF current flow, eliminating the need for additional gain control in other circuits.
