摘要: Analog electronic cochlear models need exponentially scaled filters. CMOS Compatible Lateral Bipolar Transistors (CLBTs) can create currents when biased using a resistive line with voltage difference between both ends of the line. Since these CLBTs are independent threshold voltage, current sources implemented much better matched than created MOS transistors operated in weak inversion. Measurements from integrated test chips shown to verify improved matching.
