High Throughput Circuit Design of Flash Type Analog to Digital Converter

Abstract

Analog to Digital Converters (ADCs) have a good scope of application due to their high reliability, speed, band-width, and resolution. They are used in digital signal processing devices, satellite communications, digital storage oscilloscopes, micro-controllers, RADAR processing, and digital multimeters. In this paper, we propose a high throughput circuit design that performs multiple ADC operations in parallel by using the same hardware. The proposed high throughput design can be configured with a control line to perform one 3-bit operation or two 2-bit operations in parallel. The throughput of the 3-bit Flash Type conventional ADC is increased by 10 times using the proposed hardware design. All the proposed and conventional designs are implemented with 90 nm CMOS library in Cadence Virtuoso.
