Introduction

Ronald L. Coburn is a notable inventor based in Fuquay-Varina, North Carolina. He has made significant contributions to the field of technology, particularly in the area of signal processing. With a total of 3 patents to his name, Coburn's work has had a lasting impact on various applications.

Latest Patents

One of his latest patents is the "Constant Gain Phase Lock-Loop." This invention involves a Phase Lock Loop (PLL) that receives input signals from a local area network (LAN) and recovers data and clock signals. The PLL features a charge pump that responds to pump-up or pump-down signals provided by a phase detector. Additionally, a level determination circuitry scales the charge pump current in proportion to the time elapsing between transitions in the input signals. This design ensures a constant average amps per radian gain, making it insensitive to variations in the input signals.

Another significant patent is the "Sinusoidal Signal Generator." This invention describes a high current CMOS circuit that includes a raised cosine signal generator. The generator is designed to produce a raised cosine signal waveform, with an input circuit arrangement that controls the generator's operation. The raised cosine signal generator features an output node connected to a controlled chain of CMOS inverters. The input circuit arrangement accepts an input signal and converts it into appropriate signals that drive respective inverters, preventing simultaneous conduction of inverter pairs. The off-chip driver minimizes ground bounce, electrical noise, and radiation problems caused by large current transients.
