Title: Sanjoy Kumar Dey: Innovator in Analog-to-Digital Converter Technology
Introduction
Sanjoy Kumar Dey is a prominent inventor based in Noida, India. He has made significant contributions to the field of analog-to-digital converters (ADCs) with a total of 10 patents to his name. His innovative work focuses on reducing leakage currents in ADCs, which is crucial for maintaining the accuracy of digital output values.
Latest Patents
One of his latest patents is titled "Active switch having low leakage current." This invention involves active, top-plate, n-type switch circuitry that utilizes an n-type transistor and gate-voltage control circuitry. The control circuitry generates the gate voltage to turn the transistor on and off, effectively limiting the gate-to-source voltage difference. This limitation helps to reduce GISL leakage current, which can jeopardize the accuracy of the ADC's digital output value. In specific implementations, the control circuitry adjusts the gate voltage based on the source voltage, ensuring optimal performance during the ADC conversion phase.
Another notable patent is "Passive switch having low leakage current." This invention features passive top-plate switch circuitry that includes diode-configured transistors. These transistors are connected to the top-plate node of storage capacitors, providing a diode-voltage drop that minimizes GIDL/GISL leakage current. The design ensures that the voltage at the node between two transistors differs from the top-plate node voltage, thereby enhancing the ADC's digital output accuracy.
