An operational amplifier (op amp) is a high-gain direct-coupled differential amplifier. It is an analog data ... If the input of an op amp with negative feedback receives a -180° out of phase replica of the output through the feedback network, then this will result in oscillations.
A hysteresis comparator is operated by applying a positive feedback* to the comparator. The potential difference between the High and Low output voltages and the feedback resistor are adjusted to change the voltage that is taken as a comparison reference to the input voltage for the +IN terminal.
positive feedback (this self-oscillating Class D amplifier topology is known as “SODA”), yet the audio signal may be further linearized with another negative feedback loop operating in the relatively lower frequency audio band. With the latter approach, the Class D amplifier becomes a self-contained, free-running, high frequency astable
