An Analog to Digital Converter (ADC) is a circuit which converts analog voltage signal into digital signal form. Practically most of the data is characterized using analog signals but the input to different processors cannot be an analog signal hence it needs to be converted into digital signals, so that processors will be able to read, understand and manipulate the data. The basic process in conversion involves sampling and quantization of the input signal. The continuous time domain analog signal is converted to a signal discrete in amplitude and time. In this paper we propose a novel architecture for Digital-to-Analog converter for the purpose of implementation on successive approximation register type Analog-to-Digital converter. Compared to conventional converters the differential switching enhances the resolution time, efficiency and area. The architecture implemented on 45nm reduces the capacitor and hence enhancing both timing and area of the circuit.
