Abstract
A multiplying analog-to-digital converter ('MDAC') that reduces the power consumption of the MDAC by at least 2.3 times by improving the feedback factor. The amplifier may include a feed forward approach in which the input capacitor (also referred to as 'sampling capacitor') is buffered by a common gate amplifier to improve bandwidth by removing input and parasitic capacitance terms from the global feedback loss. THe amplifier may also use an alternate form of local compensation, for example, cascode compensation. The amplifier may also further include an alternate way to reduce parasitic capacitance with a buffer.
