A Low-Voltage, Low-Power Controllable Current Amplifier for Hearing Instruments
Rob Otte, Arthur H. M. van Roermund · European Solid-State Circuits Conference · 1993
A controllable current amplifier with a control range of more than 60dB for application in a novel, completely integratable hearing instrument is presented. It operates on power supply voltages of 1V .. 1.3V. Low current consumption is aimed at. The maximum value is 93?A.
