Title: Innovations of Charles Wojslaw in Amplifier Technology
Introduction
Charles Wojslaw is an accomplished inventor based in Auburn, CA (US). He has made significant contributions to the field of radio frequency (RF) amplification. His innovative work focuses on enhancing the performance and reliability of RF amplifiers through advanced bias control techniques.
Latest Patents
Charles Wojslaw holds a patent for an "Amplifier bias control circuit." This invention involves methods and apparatus for adjusting the DC bias of an RF amplifier under varying operating conditions, such as multiple modulation techniques when no RF signal is present. The system utilizes a digitally controlled voltage source, which is programmed to maintain the amplifier's bias. This voltage source can function as a digitally controlled potentiometer. The amplifier's DC output current is converted to a voltage and compared to a programmable reference that represents the optimal amplifier bias. The output from the comparator determines the direction to adjust the voltage source. Additionally, a digital clock is activated to drive the voltage source when no RF is present. Alternatively, the amplifier's output current can be processed by a processor that determines the optimal bias, which can then be written to a data register to set the voltage on the voltage source. This system automatically compensates for changes in the amplifier's optimal bias due to aging, temperature variations, and modulation schemes.
