Abstract: A method and a MAC unit that may include accumulation unit and a multiplier. A accumulation unit that includes a first part, a second part and a third part. The first part may calculate a truncated sum. The second part may be configured to (a) receive, during each calculation cycle, a carry out of an add operation performed during a calculation cycle, (b) receive a sign bit of an intermediate product calculated during the calculation cycle; and (c) calculate, by the counter logic, a counter logic value, and (d) convert, after a start of a last calculation cycle of the calculation cycles, an output value of the counter logic to an intermediate value having a two's complement format. The third part may be configured to calculate an output value of the MAC unit based on the intermediate value and a truncated sum calculated by the first part of the accumulation unit.

Abstract: A method for charge-reuse, the method may include performing multiple repetitions of the steps of: operating a second capacitive load while the second capacitive load is disconnected from a first capacitive load; wherein the second capacitive load is a Microelectromechanical systems (MEMS) capacitive load or a Nanoelectromechanical systems (NEMS) capacitive load; electrically coupling a first capacitive load to a second capacitive load via a path that comprises an inductor; charging the first capacitive load with a second charge provided from the second capacitive load; electrically disconnecting the first capacitive load, the second capacitive load and the inductor from each other; feeding the inductor with a supply current provided by a supply circuit; disconnecting the inductor from the supply circuit and coupling the inductor to the first capacitive load; charging the first capacitive load by the inductor; electrically coupling the first capacitive load to the second capacitive load via the path that comprises the inductor; charging the second capacitive load with a first charge provided from the first capacitive load; and operating the second capacitive load while the second capacitive load is disconnected from the first capacitive load.
