Title: Peicheng Ju: Innovator in Bandgap Reference Circuits and DAC Performance
Introduction
Peicheng Ju is a notable inventor based in Berkeley Heights, NJ (US). He holds 2 patents that showcase his contributions to the field of electrical engineering, particularly in the design of bandgap reference circuits and digital-to-analog converters (DACs). His innovative work has implications for various electronic applications.
Latest Patents
One of Ju's latest patents is a low voltage bandgap reference circuit. This circuit utilizes reduced substrate area while requiring relatively low voltage. It includes a bipolar transistor with a resistor connected across the emitter-base, which sums a first current with a second current and generates a fractional voltage. The design allows for a first current that is proportional to the voltage and a second current that is proportional to a PTAT (Proportional To Absolute Temperature) current. Additionally, an impedance booster may be incorporated into the circuit. Another significant patent involves the use of current folding to enhance the performance of a current-steered DAC operating at low supply voltage. This innovation improves the performance of a single-bit cell in a DAC by decoupling the voltage swing across the load resistors from the output of the current steering device.
