Abstract
The characteristics of the recently introduced switched-MOSFET (SM) technique make it very useful in applications where programmable low-voltage filters are required, such as in hearing aid circuits. In this paper we present an SM programmable bandpass filter intended for hearing aid devices. We also address a comparison of our bandpass filter with a filter previously described in the literature, which has been implemented with the well-known switched-capacitor (SC) technique
