Onabajo Awarded Patent

January 2, 2018

ECE Assistant Professor Marvin Onabajo was awarded a patent for “Instrumentation amplifier with digitally programmable input capacitance cancellation”.


Abstract Source: USPTO

An instrumentation amplifier that includes input capacitance cancellation is provided. The architecture includes programmable capacitors between the input stage and a current feedback loop of the instrumentation amplifier to cancel input capacitances from electrode cables and a printed circuit board at the front end. An on-chip calibration unit can be employed to calibrate the programmable capacitors and improve the input impedance.
