A high gain strategy with positive-feedback gain enhancement technique
نویسندگان
چکیده
Several new CMOS very high DC-gain amplifiers that use internal positive-feedback techniques are presented. These amplifiers have a controllable gain and don't require perfect matching of transistors to achieve the high DC gain. An implementation of a sample and hold circuit constructed using one of the proposed amplifiers is described. Sin~ulation results predict a DC gain larger than lOOdB is possible without limiting the speed of the amplifier.

Partial Positive Feedback for Gain Enhancement of Low-Power CMOS OTAs
Four circuit schemes that use partial positive feedback for gain enhancement in CMOS OTAs are examined. These circuit schemes are classiied as type I and type II circuits. Type I circuits use a diierential input pair with positive feedback and type II circuits use a active load with positive feedback. As the primary emphasis of these circuits is for micropower operation, the circuits have been ...

متن کاملA high DC-gain low-power current recycling amplifier in deep sub-micron technology
A high DC-gain low-power current recycling amplifier using positive-feedback technique is presented. In the proposed amplifier, the positive-feedback signal used to enhance the DC-gain is derived from the extra nodes created by cascoding. Positive-feedback offers the ability of obtaining a very high DC-gain, ideally infinite gain, without affecting high frequency performance and stability. Unde...
