The present disclosure provides a super-regenerative transceiver with a feedback element having a controllable gain. The super-regenerative transceiver utilizes the controllable gain to improve RF signal data sensitivity and improve RF signal data capture rates. Super-regenerative transceivers described herein permit signal data capture over a broad range of frequencies and for a range of communication protocols. Super-regenerative transceivers described herein are tunable, consume very little power for operation and maintenance, and permit long term operation even when powered by very small power sources (e.g., coin batteries).

A sensing sensor includes an oscillator circuit, a base, a connection portion, and a temperature changing unit. The oscillator circuit oscillates the piezoelectric resonator. The base includes a base main body in which a depressed portion is provided and a lid portion at one side, supports the piezoelectric resonator at another side, and is for taking the oscillation frequency to an outside of the sensing sensor. The depressed portion houses the oscillator circuit. The lid portion covers the depressed portion. The connection portion is disposed at the one side of the base and connected to a cooling mechanism for cooling the base from the one side. The temperature changing unit is interposed between the piezoelectric resonator and the base, so as to cool and heat the piezoelectric resonator and transfer a heat radiated for cooling the piezoelectric resonator from the other side of the base to the one side.

An integrated circuit may include oscillator circuitry having a resonator formed from fin field-effect transistor (FinFET) devices. The resonator may include drive cells of alternating polarities and sense cells interposed between the drive cells. The resonator may be connected in a feedback loop within the oscillator circuitry. The oscillator circuitry may include an amplifier having an input coupled to the sense cells and an output coupled to the drive cells. The oscillator circuitry may also include a separate inductor and capacitor based oscillator, where the resonator serves as a separate output filter stage for the inductor and capacitor based oscillator.
