Title: Innovations of Subramaniam Shankar
Introduction
Subramaniam Shankar is a notable inventor based in Thousand Oaks, CA (US). He has made significant contributions to the field of electrical engineering, particularly in the development of advanced circuit designs. With a total of 5 patents to his name, Shankar continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is the "DC blocking circuit with bias control and independent cut-off frequency for AC-coupled circuits." This invention addresses the challenge of blocking undesired input direct current in AC-coupled broadband circuits. The circuit features a capacitor coupled to an input port and a common node, which receives an RF input signal. It also includes a current source that supplies a DC current to the common node, leading to a bias current at the output port. Additionally, a variable voltage source is integrated to control the bias current, ensuring that the RF output signal remains free of any input direct current.
Another significant patent is the "Variable gain amplifier with stable frequency response." This variable gain amplifier is designed to provide a stabilized frequency response while allowing for a widened gain control range. It incorporates a resistor-capacitor compensation network between differential current input ports and corresponding emitter nodes of cross-coupled transistors. This design desensitizes gain control voltages to system noise and stabilizes the frequency response over a bandwidth ranging from 1 GHz to 60 GHz, achieving a gain control range of up to 12 dB without increasing power consumption.
