These circuits need a big number of ADCs to reach the required resolution at a specified speed. Moreover, nowadays power dissipation has become a key performance to be considered in analog designs, specially in those developed for portable devices. Design of such circuits is a challenging task which requires a combination of the most advanced digital circuit, the analog expertise knowledge and an iterative design. Amplifier sharing has been a commonly used technique to reduce power dissipation in pipelined ADCs. In this paper we present a partial amplifier sharing topology of a 12 bit pipeline ADC, developed in 0.35 mum CMOS process. Its performance is compared with a conventional amplifier scaling topology and with a fully amplifier sharing one.
