Abstract
Amplifiers can be found in pipelined ADCs and pipelined-SAR ADCs as inter-stage amplifiers. The amplifiers can in some cases implement and provide gains in high speed track and hold circuits. The amplifier structures can be open-loop amplifiers, and the amplifier structures can be used in MDACs and samplers of high speed ADCs. The amplifiers can be employed without resetting, and with incomplete settling, to maximize their speed and minimize their power consumption. The amplifiers can be calibrated to improve performance.
