Latest Patents

Shih is associated with 1 patent, titled “Bandgap Reference Circuit with Leakage Current Compensation.” The invention uses two bipolar junction transistors biased at different current densities to establish a difference between their base-emitter voltages. One transistor helps determine a complementary-to-absolute-temperature signal, while a differential sensing resistor and feedback circuit help derive a proportional-to-absolute-temperature signal. The circuit combines these signals to generate a reference voltage with a zero temperature coefficient, while compensating for leakage current.
