Title: The Innovations of Robert G. Meyer
Introduction
Robert G. Meyer is a notable inventor based in Berkeley, California, recognized for his contributions to the field of electronics. With a total of 13 patents to his name, he has made significant advancements in signal attenuation technology. His work has had a profound impact on the design and functionality of radio frequency devices.
Latest Patents
Among his latest patents, the "Low Distortion MOS Attenuator" stands out. This attenuation circuit utilizes a voltage-controlled variable resistance transistor as a signal attenuator for receivers operating in the zero Hz to about 30 MHz range. The transistor operates in the linear region to enhance the resistance characteristics used for signal attenuation. In practical applications, this circuit serves as an RF attenuator for AM radio broadcast receivers and amplifiers equipped with automatic gain control. Additionally, multiple attenuation circuits can be connected in parallel, each featuring a differently sized variable resistance transistor, to create sequentially activated stages that expand the range of attenuation while minimizing distortion.
Another significant patent is the "Voltage Controlled Variable Attenuator." This device is designed to be connected to a transmission path, providing variable attenuation of signals, particularly radio frequency signals. The variable attenuator includes at least one transistor, which can switch between an open configuration that prevents current flow and a closed configuration that allows partial current flow. A resistive component is also integrated to mitigate non-linear effects during the transition of the transistor. This configuration enables effective signal attenuation when the transistor is in the closed state.
