Abstract
We introduce the autozeroing floating-gate (AFGA) second-order section. We built this second-order filter where the corner frequency and Q are electro nically tunable based on a classic filter topology and principles of operat ional transconductance amplifiers. We built this second-order filter using three AFGAs-our Boating-gate amplifier that sets its operating point by the interaction of hot-electron injection and electron tunneling.
