This circuit shown above is capacitorless relaxation oscilla

This circuit shown above is \"capacitor-less\" relaxation oscillator. The circuit operates from dual +/- 12V supply and produces waveforms with ~ 300kHz. PART 1: Specify hysteretic comparator type (inverting or non-inverting) Identify the components that implement this hysteretic comparator.

Solution

The LT1008 precision operational amplifier is used as non inverting mode

Tl081 is general purpose FET input operational amplifier used in inverting mode

hence this circuit is inverting comparator

This uses The LT1008 precision operational amplifier,Tl081 is general purpose FET input operational amplifier two zener diodes and resistors
