Precision Clamp Circuit ⭐ Superdiode Theory, Design Example & SPICE Simulation 👍 #diode #opamp

In this video, we dive into the Precision Clamp Circuit—a smart analog solution that uses an op-amp and diode in a negative feedback loop (superdiode) to eliminate the diode’s voltage drop (~700 mV). This allows for accurate signal clamping, even at low voltages.

First, we discuss the operation principle and the for a negative feedback loop in order to eliminate the diode voltage drop (700 mV). Then, we will determine the expression for the output voltage for both negative and positive clamping, and the extreme values of the op-amp's output voltages. In the final part, we will discuss a detailed example in which we discuss the complete circuit with actual component and op-amp model. We will work out the calculations step by step and verify our calculations in TINA-TI SPICE simulations.
