Abstract: A flash analog-to-digital converter (ADC) receives an input control signal and performs coarse tuning of a frequency of an output signal, produced between first and second nodes having an inductance coupled therebetween. The flash ADC quantizes an operating frequency range for the output signal produced between the first and second nodes as M·Δf, where M is an integer from 0 to N−1, where N is a number of intervals into which a frequency range for the output signal is divided, and where Δf is a resulting frequency step produced by the quantizing. The value of M is generated based upon the input control signal and a word controlling switches of a plurality of switched capacitance circuits associated with the first and second nodes to close ones of those switches associated with the control word to coarsely tune the frequency of the output signal.

Abstract: An input receives a radio frequency (RF) signal having an interfering component superimposed thereon. The RF signal is mixed with a local oscillator (LO) signal and down-converted to an intermediate frequency (IF) to generate a mixed signal which includes a frequency down-converted interfering component. The mixed signal is amplified by an amplifier to generate an output signal. A feedback loop processes the output signal to generate a correction signal for cancelling the frequency down-converted interfering component at the input of the amplifier. The feedback loop includes a low-pass filter and a amplification circuit which outputs the correction signal.

Abstract: A first RF-to-DC circuit receives a radiofrequency signal and produces a first converted signal delivered to an energy storage circuit. A second RF-to-DC circuit, which is a down-scaled replica of the first RF-to-DC circuit, produces a second converted signal from the radiofrequency signal that is indicative of an open-circuit voltage of the first RF-to-DC circuit. The first RF-to-DC section includes N sub-stages, with a sub-set of sub-stages being selectively activatable. A window comparison of the second converted signal generates a first signal and a second signal indicative of whether the second converted signal is within a range of values proportional to a voltage reference signal. The sub-set of sub-stages is selectively deactivated, respectively activated, when the performed window comparison has a first result, respectively, a second result.

Abstract: A circuit includes a phase-frequency-detector generating first and second digital control signals indicative of phase differences between an input reference-signal and an output-signal, a charge-pump generating a control-signal based upon the first and second digital control signals, and an oscillator-circuit. The oscillator-circuit includes an active core coupled between first and second nodes, with a tunable resonant circuit a set of capacitances selectively connected between the first and second nodes, wherein a tap between the first and second variable capacitances receives the control-signal for tuning the tunable resonant circuit. A timer-circuit generates a timing-signal based upon the input reference-signal and a reset-signal. A calibration-circuit controls which capacitances of the set of capacitances are connected between the first and second nodes, in response to the timing-signal and a comparison between a threshold and a voltage-signal that is based upon auxiliary pulsed currents generated based upon the first and second digital control signals.
