A design procedure that determines the combination of linear settling time (i.e. gain bandwidth) and slew rate that minimizes an amplifier total power consumption, while complying with a given total settling time specification, is presented. The method is presented for a Miller OTA, but can be generalized to other architectures. The proposed approach also provides the optimum combination of the gm/ID ratios of the input and output transistors and the transistor design corresponding to this… CONTINUE READING
