This paper presents an input-powered energy-harvesting interface circuit that eliminates standby power consumption by automatically shutting down when the ac input voltage amplitude is too low for ...

In piezoelectric energy harvesting, a synchronous charge extraction (SECE) interface circuit can be used to improve power conversion efficiency. Previous studies usually use additional displacement ...

However, these current mirror circuits have quite a low input impedance which (without an op-amp buffer, and if a buffer, why not just use the top circuit) will excessively load the typical ...

Design issues for translating a DC coupled unipolar input to a differential ADC at some Vcm . It is a challenging task to provide an ADC interface circuit ...

The subscriber line interface circuit (SLIC) within the modem has the additional burden of ringing the phone as well as providing loop current while a conversation is taking place.
