Title: Innovations of John E Vasa

Introduction

John E Vasa is a prominent inventor based in Irvine, CA, known for his significant contributions to the field of wireless communication. With a total of 16 patents to his name, Vasa has developed innovative technologies that enhance the performance of wireless receivers and transmitters.

Latest Patents

One of his latest patents is titled "Circuits, systems, and methods for managing automatic gain control in quadrature signal paths of a receiver." This invention provides a system for closed-loop gain control in WCDMA mode and open-loop control in EDGE/GSM mode. The gain control is distributed across analog devices and a digital scaler in a wireless receiver. In WCDMA mode, a loop filter generates an error signal that is forwarded to both analog and digital control paths. The analog control path includes a first adder, a programmable hysteresis element, and a lookup table. The analog control signal is responsive to thresholds, which, when used in conjunction with a previous gain value, determine a new gain value. The digital control path includes a second adder, a programmable delay element, and a converter. A control word is responsive to a difference of the error signal, a calibration value, and the analog control signal. Additionally, blocker detection is provided in the WCDMA mode of operation. Another notable patent is the "Method for fast automatic power control of wireless transmitters." This circuit includes a transmit path to receive an input signal and generate an output signal at a transmit power level according to a power target signal. The circuit also features a gain corrector to adjust the power level of the output signal based on the power target signal and a delay for time-aligning signals.
