Title: The Innovations of Carl F. Windnagle

Introduction

Carl F. Windnagle is a notable inventor based in Hudson, MA, known for his contributions to the field of electronics. He has made significant strides in the development of output buffer technology, which is crucial for various electronic applications. His innovative approach has led to the creation of a patented technology that enhances the performance of CMOS output buffers.

Latest Patents

Windnagle holds a patent for a "Staged CMOS Output Buffer." This invention features multiple output transistors connected in parallel, driven by corresponding predrivers. Each predriver is designed with a first input that can activate an inactive output transistor and a second input that can deactivate an active output transistor. The input to the output buffer is directly coupled to the second input of both predrivers, ensuring that the output transistors are turned off at the beginning of the switching process. Additionally, a resistor-capacitor (RC) circuit is integrated between the first inputs to stagger the predriver turn-on times, effectively reducing the peak and slope of the switching current. The predriver also utilizes chains of pass transistors to achieve tri-state functionality and simultaneous turn-off, which is essential for the staged configuration. Furthermore, a split termination is employed to minimize switching current, particularly during NMOS-PMOS crossover.
