Design and simulation of a two-stage CMOS OpAmp in Cadence Virtuoso. Verified via PVT corners and Monte Carlo analysis.

Design, simulation(LTspice), and automated Python characterization of a Two-Stage Miller-Compensated CMOS Op-Amp in TSMC 0.18µm. Achieved 71 dB Gain, 52.1 MHz GBW, 63.3° Phase Margin, and 53.7 V/µs Slew Rate with deep-submicron short-channel tuning.

This example demonstrates the different OPA peripheral modes of operation. This firmware is pre-loaded onto the Q41 Curiosity Nano development boards.

This MCC based MPLAB X example shows how to calibrate the gain and offset of the OPAMP when configured as a Programmable Gain Amplifier (PGA). The internal DAC and ADC are used to perform the calibration procedure. No external components are required.

Two-stage 65 nm CMOS operational amplifier designed in Cadence Virtuoso using the gm/Id methodology.

These MPLAB X MCC examples in Getting Started with Analog Signal Conditioning (OPAMP) (TB3286), show how the OPAMP can be used on the AVR DB family of microcontrollers. The OPAMP peripheral features up to three internal operational amplifiers.

This MCC based MPLAB X IDE example shows how to use the Analog Signal Conditioning (OPAMP) peripheral to implement a constant-current driver using just one external resistor. The constant current amperage setting can be adjusted using firmware control.
