Abstract:
In one example an amplifier includes a bias circuit, an open-loop gain stage including a first PMOS having a gate coupled to a first node, a source coupled to a second node, a drain coupled to a third node, and a bulk coupled to the bias circuit, a second PMOS having a gate coupled to a ground node, a source coupled to the second node, a drain coupled to a fourth node, and a bulk coupled to the bias circuit, a first NMOS having a drain and a gate coupled to the third node and a source coupled to a fifth node, a second NMOS having a drain coupled to the fourth node, a gate coupled to the third node, and a source coupled to the fifth node, an adjustable resistor coupleable between the third and fourth nodes, and a buffer stage coupled to the open-loop gain stage.

Claim (Index 1):
An amplifier, comprising:\n a bias circuit configured to generate a bias voltage with respect to ground; and an open-loop gain stage comprising:\n a first p-type metal oxide semiconductor field effect transistor (MOSFET) (PMOS) having a gate terminal coupled to a first node, a source terminal coupled to a second node, a drain terminal coupled to a third node, and a bulk connection coupled to the bias circuit; \n a second PMOS having a gate terminal coupled to a ground node, a source terminal coupled to the second node, a drain terminal coupled to a fourth node, and a bulk connection coupled to the bias circuit; \n a first n-type MOSFET (NMOS) having a drain terminal and a gate terminal coupled to the third node and a source terminal coupled to a fifth node; \n a second NMOS having a drain terminal coupled to the fourth node, a gate terminal coupled to the third node; and a source terminal coupled to the fifth node, wherein the gain stage is configured to couple to an adjustable resistor positioned between the third node and the fourth node; and \n a buffer stage coupled to the open-loop gain stage at the fourth node and comprising a super source follower.
