With a total of nine patents to his name, Petersen's work reflects a deep understanding of circuit design and innovation.
Latest Patents
Among his latest patents is the "CMOS process and circuit including zero threshold transistors." This invention presents a method of threshold adjust implantation, which involves implanting some of the PMOS FETs' channels on a CMOS circuit. The goal is to achieve a threshold voltage of substantially zero volts. This process includes an additional implantation of ions into the PMOS FET's channels, enhancing the functionality of the circuit.
Another significant patent is the "Programmable operation transconductance amplifier." This invention features a digitally programmable Bessel filter that consists of multiple serially connected stages or biquads. Each biquad includes several programmable operational transconductance amplifiers. The first stage of the filter provides an all-pass equal amplitude response, while subsequent stages offer pulse slimming and a sixth-order Bessel low pass function. The operational transconductance amplifiers are controlled by fine-tuning and coarse-tuning signals generated in a phase-locked loop.
