Introduction

Siddhartha Gopal Krishna is a prominent inventor based in New Delhi, India. He has made significant contributions to the field of electronics and signal processing, holding a total of seven patents. His work focuses on developing advanced circuits that enhance the performance and reliability of electronic systems.

Latest Patents

One of his latest patents is the "Input signal mismatch detection circuit." This system is designed to detect mismatches between first and second input signals. It includes first and second analog-to-digital converters, a time-division multiplexing circuit, first and second processors, a time-division de-multiplexing circuit, and a gating circuit. The first processor features a first sinc filter, a first trimmer, a first infinite impulse response (IIR) filter, and a first high pass filter (HPF). The second processor is equipped with a second sinc filter, a second IIR filter, and a second HPF. Notably, the bandwidth of the second IIR filter and the second HPF is greater than that of the first IIR filter and the first HPF. The transfer function of the first IIR filter and the first HPF utilizes floating-point coefficients, while the second IIR filter and the second HPF use coefficients that are an integral power of two.

Another significant patent is the "Current detection circuit with over-current protection." This invention involves threshold detection for load current on a bus. It generates an output current representative of the load current using a transconductance circuit. The output current is sampled during a quiescent phase of the bus to produce a sample current. A compensation current, proportional to the transconductance gain associated with the transconductance circuit, is generated based on the sample current. The combined current is produced by combining the output current, sample current, compensation current, and a reference current representative of a threshold value for the load current. A discriminator is used during an active phase of the bus to output a first value when the sum current exceeds the threshold value and a second value when it is less than the threshold value.
