This paper proposes a 10-bit pipelined Analog to Digital Converter (ADC) which incorporates various techniques for lesser power and higher performance. The proposed method reduces the computational burden while comparing to the modified Monte-Carlo (MC) method. Pipelined ADC has N number of stages, it has higher resolution and higher frequency of conversion while comparing to other ADCs. The proposed ADC employs five 2.5bit gain stages; instead of 1.5bit gain stages for high accuracy. This method is implemented in the Tanner Software with the Generic 250nm library at a maximum power supply of 5V. The maximum frequency attained is 150MHz; and the ADC exhibits a SNR of 61.96dB. It also attains a 10bits as effective number of bits at the maximum sampling rate.
