ANVIL · Analog Sizing Workbench (Beta)

Pick a 5T OTA or a two-stage Miller op-amp, enter your gain, bandwidth, phase margin, power, slew and swing targets, and an automated loop sizes the transistors with real ngspice simulations. The best design is then checked across 45 process, temperature and supply corners, and every number links to the simulation that produced it. The simulator is a WebAssembly build of ngspice that runs in your browser, using predictive 45 nm models, not a foundry PDK.

The workbench needs JavaScript and WebAssembly enabled. Read the documentation.
