Abstract— In this paper, a resonant microelectromechanical (MEMS) 2×1 bit multiplier is presented for the first time. The proposed multiplier features 3 inputs and 2 outputs, implemented using two identical clamped-clamped beam microresonators. Each designed microresonator includes two electrodes for logical inputs, one drive electrode for applying the input signal, and one sense electrode for receiving the output signal. The input signal frequency applied to the drive electrode is set to the natural resonant frequency of the microresonators, which is 273 kHz. If the output signal received from the sense electrode matches this frequency, it is considered as a logical "1"; otherwise, it is considered as a logical "0". The applied DC bias voltage to the microresonators is 15V, and the logical input voltages applied to the electrodes range from 0 to 5V. These voltages are selected to induce the maximum frequency change in the microresonators with minimal voltage variations. The proposed multiplier can be used in applications such as the Internet of Things (IoT), where high speed is not critical but extremely low energy consumption is required. The designed MEMS multiplier is a more suitable option in terms of energy consumption and component count compared to transistor-based logic circuits
