Introduction

Dwight Birdsall is a notable inventor based in Fort Collins, Colorado. He is recognized for his contributions to the field of electronics, particularly in amplifier circuits. His innovative work has led to the development of a unique patent that enhances the performance of track-and-hold circuits.

Latest Patents

Dwight Birdsall holds a patent for a "Track and Hold Circuit with Clamp." This invention is a track-and-hold amplifier circuit designed to improve hold mode isolation. The circuit features an input circuit that buffers an input signal connected to a switching transistor. A clamping transistor is linked to the base of the switching transistor, while a hold capacitor is connected between the emitter of the switching transistor and circuit ground. The differential amplifier circuit receives both track and hold signals, allowing the switching circuit to charge the hold capacitor when the track signal is present. When the hold signal is received, the switching transistor opens, storing the voltage representative of the input signal on the hold capacitor. The clamping transistor ensures that the voltage at the base of the switching transistor remains stable, making the held signal independent of the input signal.
