Abstract: An electronic circuit for detecting an ultra-wideband pulse, the electronic circuit comprising an analog input terminal configured for connection to an ultra-wideband antenna, a low noise amplifier connected to the analog input terminal and configured to amplify one or more ultra-wideband pulses received via the ultra-wideband antenna, and a comparator connected to the low noise amplifier and configured to generate a wake-up trigger signal for ultra-wideband pulses exceeding a pre-defined pulse amplitude threshold.

Abstract: An electric amplifier circuit for amplifying an output signal of a microphone comprises a supply input terminal (V10) to apply a supply potential (VDDA) for operating the electric amplifier circuit and a differential amplifier (110) having a first input terminal (E110a) for applying the output signal of the microphone (20), a second input terminal (E110b) and an output terminal (A110) for outputting an amplified output signal (OUT) of the microphone (20). A feedback path (FP) is provided between the output terminal (A110) of the differential amplifier (110) and the second input terminal (E110b) of the differential amplifier (110). A charge supplying circuit (120) is coupled to the feedback path (FP) to supply an amount of the charge to the feedback path (FP) in dependence on the supply potential (VDDA). The amount of charge supplied to the feedback path may be dependent on a change of the supply potential (VDDA).
