Analog comparators are amplifiers that compare the magnitude of voltages at two inputs. An analog comparator is an operational amplifier with negative feedback removed, and with no feedback and very ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed ...

Pulse width modulated (PWM) amplifier chips generate a current that switches between high and low output levels. Sample-and-hold amplifier chips freeze analog voltage instantly. During this process ...
