Abstract

For the first time, this paper demonstrates a resonant calorimeter based on thermal actuation - piezoresistive detection resonators, employing physical self-oscillation and achieving a high-quality (Q) factor. By supplying a direct constant (DC) voltage Vdc, the N-type silicon resonator oscillates at its natural frequency. The output signal in the form of an alternating voltage (AC) and is transduced by two piezoresistive nano-beams. The resonant frequency is found to be a linear function of the thermal perturbation generated by an on-chip micro-heater. With a specific value of Vdc, a bias instability as low as 11 ppb and a power resolution of 690 nW is achieved in ambient conditions.
