Abstract :
A directional hearing aid adapter was designed and implemented using dynamic translinear (DTL) circuit techniques. The signal-processing core was optimized to yield minimum current consumption for the specified dynamic range. In this paper the design and implementation of the core is presented. It consumes a current of 40 μA at a supply voltage of down to 1.0 V having a total integrated capacitance of 400 pF for a dynamic range of 50 dB
