摘要：

In this paper we present a new; adaptive spatial-derivative circuit for use in CMOS image sensors. The circuit removes its offset as a natural part of its operation using a combination of electron tunneling and hot-electron injection to add or remove charge on a floating-gate of an auto-zeroing amplifier: We designed, fabricated and successfully tested a chip, with the circuit. Test results show that the circuit reduces the offsets by more than an order of magnitude.
