Abstract
In this paper, the design and measurement of al-V translinear integrat or and its application in a controllable second-order lowpass filter f or hearing instruments is presented. A semicustom version of the filte r has been integrated in a standard 2-mu m, 7-GHz, bipolar IC process and operates at voltages down to 1 V, consumes only 6 mu A, and has a dynamic range of 57 dB for a total harmonic distortion below 2%. Its c utoff frequency is linearly adjustable in octaves from 1.6 to 8 kHz.
