A Low-Voltage Fully-Monolithic AX-Based Class-D Audio ...
http://www.ece.mcgill.ca/~hamoui/FILES/PUBLICATIONS/01257193.pdf
This paper presents a single-chip digital audio amplifier based on a delta-sigma (a) modulator and a power- eficient switching (class-D) output-stage without intermediate filtering. Fabricated in a 0.18-pm standard digital CMOS process, this audio ampl$er can operate from a single power-supply of 1.8V down to 1 without

This paper presents a Class D amplifier output stage with low Total Harmonic Distortion (THD) and high Power Supply Rejection Ratio (PSRR). The Class D output stage reduces the non-linearities and supply noise by means of a second-order negative feedback loop embodying a single stage second-order integrator and a Schmitt trigger comparator.

Designing the ultimate monolithic amplifier. Fifteen years ago, my reference amplifier was a current feedback power amp, with 10 W @ 8 Ohm operating in A class, 25 W max, with fairly simple and clean topology (diamond input, another pair of voltage transistors, and output current pair), and no less than 200.000 uF supply capacity.
The Monolithic Operational Amplifier: A Tutorial Study
https://web.ece.ucsb.edu/Faculty/rodwell/Classes/ece2c/resources/an-a.pdf
1is based on the following: this circuit contains, in simplified form, all of the important elements of the most commonly used integrated op amps. It consists essentially of two volt-age gain stages, an input differential amp and a common emitter second stage, followed by a class-AB output emitter follower which provides low impedance drive to ...
