Abstract:
An apparatus and method for recycling and reusing charge in an electronic circuit. The apparatus includes at least one capacitor coupled to a circuit block in the electronic circuit, the capacitor being configured to collect current charge consumed by the circuit block when set to a charge collection mode, and a voltage level comparator configured to detect a fully charged state when the capacitor is fully charged. Further, the apparatus includes a first electrical switch configured to allow, once the fully charged state is detected, the capacitor to switch to a discharge mode for discharging the current charge collected back into the power supply for reuse by the electrical system and a second switch configured to allow, after the capacitor has fully discharged the current charge collected, the capacitor to switch back to the charge collection mode, such that, the current charge is recycled and reused by the electrical system.
