Title: Innovations of Parthasarathy Sampath

Introduction

Parthasarathy Sampath is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of analog-to-digital conversion technology. With a total of three patents to his name, his work focuses on enhancing the performance and efficiency of analog-to-digital converters.

Latest Patents

One of his latest patents is an offset compensated analog-to-digital converter. This oversampling ADC includes a quantizer that adds an offset error to each oversampling sample. If not addressed, this offset error can limit the ADC's performance. The existing methods to eliminate the offset often increase circuit size and slow down the ADC's operation. His invention provides a solution by offering a small and fast ADC that effectively reduces or removes the offset error. This innovation is particularly useful in high-performance applications, such as high-speed image sensors.

Another significant patent involves imaging pixels with improved analog-to-digital circuitry. This technology includes ADC circuitry that generates a digital output code from an analog input voltage. The circuitry comprises a series of capacitors, including a first set of binary-mapped capacitors and a second set with capacitances less than binary-mapped values. During successive-approximation operations, each bit of the digital output code is produced using a corresponding capacitor. This advancement allows digital processing circuitry, such as an image processor, to generate a digital value from the output code by multiplying the bits with respective weights based on the capacitance of the capacitors.
