Title: Innovations of Mark A Willi
Introduction
Mark A Willi is a notable inventor based in Marion, IA (US). He has made significant contributions to the field of radio frequency technology and emitter-coupled logic circuits. With a total of 6 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is the "Active Ring Mixer," which is an active ring mixer circuit designed for use in a receive or transmit channel of an RF radio. This innovative circuit comprises multiple transistor pairs arranged in a ring and biased into an active or saturation region. The first input is adapted to receive an RF signal, which is electrically combined with the transistor pairs to provide negative feedback. The second input receives a local oscillator signal, and the output provides a mixed signal. This mixer circuit is advantageous as it induces minimal low-frequency spurs that could interfere with radio operation, while also significantly reducing power consumption and noise figure.
Another notable patent is the "Frequency Enhanced Emitter Coupled Logic Topology." This invention includes emitter-coupled logic circuits that feature a plurality of fT-doubler circuits. Each fT-doubler circuit consists of multiple transistors arranged to behave as a single enhanced transistor, achieving a higher effective unity current gain frequency. This configuration increases the operating frequency capability of the emitter-coupled logic circuit, showcasing Mark's innovative approach to circuit design.
