  • Ultra-low-power oscillator with DC-only sustaining amplifier
    Patent number: 10924060
    Abstract: An ultra-low power (ULP) oscillator that down-converts the current of a resonator to DC, then amplifies it when its still in DC, followed by up-converting the amplified signal back to the oscillation frequency. The disclosed oscillator eliminates the minimum transconductance (gm) requirement of a Pierce oscillator, by processing the signal at DC. In addition, the circuit only requires the DC amplifier's feedback resistor to be greater than the resistive loss of the resonator, i.e., Rf>Rm.
    Type: Grant
