  • Publication number: 20230421136
    Abstract: An integrated circuit may include one or more circuits coupled to capacitance multiplier circuitry. The capacitance multiplier circuitry may include a capacitor, fixed and tunable resistances, and a transconductance circuit. The tunable resistance can be adjusted to control the overall capacitance of the capacitance multiplier circuitry. The transconductance circuit may include a transistor having a drain terminal coupled to a first electrical component and a source terminal coupled to a second electrical component. The first electrical component may be a diode-connected transistor, a direct shorting wire, a resistor, an inductor, or a current source. The second electrical component may be a current source, a direct shorting wire, a resistor, an inductor, or another diode-connected device. Configured in this way, the capacitance multiplier circuitry can provide a large adjustable amount of capacitance without a voltage drop and without consuming a large amount of power.

  • Patent number: 11791856
    Abstract: An electronic device may include wireless circuitry with a baseband processor, a transceiver, and an antenna. The transceiver may include a mixer that outputs signals to a transimpedance amplifier. The mixer has an output impedance that varies depending on the frequency of operation. An adjustable resistance can be coupled to the input of the transimpedance amplifier. A control circuit can tune the adjustable resistance to compensate for changes in the output impedance of the mixer as the transceiver operates across a wide range of frequencies.

  • Patent number: 11012045
    Abstract: A variable gain amplifier circuit is disclosed. In one embodiment, an amplifier circuit includes first and second stages. Each stage includes one or more inverter pairs, with one inverter of each pair coupled to receive an inverting component of a differential signal and the other inverter of the pair coupled to receive a non-inverting component. The first stage receives a differential input signal and produces an intermediate differential signal. The second stage receives the intermediate differential signal and produces a differential output signal, the differential output signal being an amplified version of the differential input signal.
