Abstract

In this paper, the core of a universally applicable analog integrated circuit for hearing instruments is presented: a microphone preamplifier and an input-controlled automatic gain control with an adjustable knee level. The test chip demonstrates operation down to 1.05 V and a current consumption between 80 and 125 ¿A. The full-custom chip area in a 2.5¿m BiCMOS process (using only vertical NPNs and lateral PNPs) amounts to 0.56 mm2.
