Abstract: A method and system for data logging in a listening device is provided. The system includes a digital signal processing (DSP) entity, which performs normal hearing aid audio and system processing, a level translating module, and a non-volatile (NV) memory. The NV memory is used to store logged data. During the hearing aid audio processing, the DSP entity communicates with the NV memory via the level translating module. The level translating module performs voltage-translation during data logging to a communication signal between the DSP entity and the NV memory.

Abstract: Disclosed is an Amplifier (7) comprising an output driver with a first output stage (4) and a second output stage (5), where an input signal is applied non-inverted to the first output stage and inverted to the second output stage, characterized in that said input signal is applied with delay to one of the output stages (4, 5).

Abstract: The converter has a three decision range conversion algorithm using ternary values. The converter has a single unipolar reference voltage source (Vr) and computing method (MC) to establish a voltage value. The voltage value is determined by determining a sum value from the voltage calculated during the previous iteration, and a value which is the product of the ternary value during the preceding iteration and the reference voltage. Computing is by switched capacitors (Cr, C1, C2) connected to a single operational amplifier (11). This provides a more compact circuit with less surface integration having a smaller current requirement whilst having a good conversion quality for applications such as hearing aids.
