Title: Kevin D Kolwicz: Innovator in CMOS Technology

Introduction

Kevin D Kolwicz is a notable inventor based in Allentown, PA (US), recognized for his contributions to integrated circuit technology. He holds a total of 4 patents, showcasing his innovative approach to solving complex engineering challenges.

Latest Patents

One of Kolwicz's latest patents is titled "Dynamic CMOS current surge control." This invention addresses the issue of large current surges that occur during the power-up of integrated circuits with numerous transmission gate logic stages. The problem arises from the floating input node of complementary inverters, which causes current to flow briefly before clock pulses arrive. Kolwicz's invention provides a DC voltage on the gates of the pass transistors until the system clock pulses arrive, effectively eliminating the floating node. Additionally, an optional periodic window may be generated to examine the system clock after power-up, allowing for the detection of a loss of clock condition.

Another significant patent is the "Method of manufacturing a CMOS cell array with transistor isolation." This technique introduces a new approach for forming CMOS custom logic circuits by replacing the traditional field oxide isolation with transistor isolation. The boundaries between the cells are formed by transistors that are permanently 'off', which streamlines the manufacturing process. This innovation reduces the need for separate p+ and n+ source/drain diffusions for each cell, thereby decreasing the turnaround time associated with custom logic circuit layout and design.
