Abstract :
This paper presents a novel 13-bit digital RMS calculation unit, specifically designed to be integrated together with sensor and interface circuits in complete microsystems. The circuit exploits oversampling techniques (bitstream processing) to eliminate the area inefficient multipliers required in traditional RMS calculation units. The proposed approach leads to a significant reduction (almost 30%) in the silicon area required to implement the RMS calculation algorithm for a 13 bit word
