  • Abstract
    In this paper, we present the design and IC implementation of a 3V micropower programmable transconductance-C (gm-C) filter set for hearing aid applications. The filter set comprises 3 biquads, including a proposed high pass biquad which features the simplest structure to date. The filter set features a novel architecture in that it may be configured as a single 3-channel device or a single or cascade of two or three biquads. This filter set was implemented in IC with an area of 2.4×2.6 mm2 using a 1.2 μm CMOS process. The measurement results show that the prototype ICs dissipated a maximum of 250 μW
