Abstract
An integrated circuit apparatus comprises a first stage amplifier and a second stage amplifier. The first stage amplifier is characterized by a cross-coupled integrated layout providing a rail-to-rail swing and a linear gain, A, substantially defined as A=g.sub.m r.sub.o '. The second stage amplifier is coupled to the output of the first stage amplifier and comprises a high-voltage integrated circuit transistor with an AC feedback circuit, the AC feedback circuit comprising, in series, a capacitor, a N+ resistor and an N-WELL resistor, wherein the output of the second stage amplifier is used to directly drive an inductive load.
