Title: Douglas L Hiser: Innovator in CMOS Technology
Introduction
Douglas L Hiser is a notable inventor based in Berkeley, CA (US), recognized for his contributions to the field of CMOS technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a method of fabricating a self-cascoding CMOS device. This invention involves a self-cascoding transconductance circuit that includes cascoding and current sink/source FETs, which are serially connected with their gates tied together to receive an input voltage. The design ensures that the current sink/source FET operates in its saturated region by having a threshold voltage that is at least 0.1 volts less than that of the cascoding FET. Additionally, a CMOS structure implementing this circuit features two doped threshold adjust regions formed beneath a gate electrode, allowing for effective operation of the FETs. Another significant patent is the programmable operation transconductance amplifier, which includes a digitally programmable Bessel filter composed of multiple serially connected stages. This filter provides various functionalities, including pulse slimming and a sixth-order Bessel low pass function, controlled by fine and coarse tuning signals generated from a phase-locked loop.
