Title: Innovations of Joshua C. Park
Introduction
Joshua C. Park is a notable inventor based in Medford, MA (US). He has made significant contributions to the field of technology, holding a total of six patents. His work primarily focuses on advancements in radio frequency output and voltage reference circuits.
Latest Patents
Among his latest patents is the "Multistage modulation architecture and method in a radio." This invention involves a multiple-stage transmitter where an analog signal is modulated and mixed to produce a radio frequency output. A unique feature of this design is that a single frequency synthesizer is utilized instead of multiple synthesizers, enhancing efficiency. In a two-stage system, the first and second dividers receive the output from the frequency synthesizer, delivering mixing signals to each stage. The modulus of each divider can be selected to minimize spurious signals.
Another significant patent is the "Bandgap reference voltage circuit." This circuit includes a bandgap start-up circuit that initiates the operation of the bandgap reference voltage circuit. It also features a bandgap core circuit that develops a bandgap reference voltage and a bandgap output circuit that supplies this voltage. The design ensures that the start-up circuit connects to a low impedance leg, eliminating the possibility of metastable operation. This circuit is particularly useful in battery-powered units with reduced supply voltages, such as 1.7V.
