Abstract :
We introduce the Autozeroing Floating-Gate Second-Order Section. We built this second-order filter where the corner frequency and Q are electronically tunable based on a classic filter topology and principles of OTA amplifiers. We built this second-order filter using three AFGAs-our floating-gate amplifier that sets its operating point by the interaction of hot-electron injection and electron-tunneling
