Abstract
A new approach to the design of a low-power cascadable analogue filter for applications such as silicon cochlea implants is described. One section of a possible silicon cochlea based on a second-order continuous-time filter employing MOS technology operating in weak inversion is presented. The idea is based on the recently proposed log-domain filter approach used previously in bipolar technology
