Abstract: Phase Locked Loop, PLL, circuitry comprising a phase detector configured to generate a first pulse signal comprising at least one first pulse, a property of each first pulse being indicative of a phase difference between a reference signal and a feedback signal; a pulse repeater circuit configured, based on the first pulse signal, to generate a second pulse signal comprising, for each first pulse, a second pulse generated by repeating the corresponding first pulse; and an oscillator configured to generate the feedback signal and control a frequency of the feedback signal based on the second pulse signal.

Abstract: Signal-generation circuitry comprises: a differential amplifier comprising first and second input transistors, connected along respective current paths and having control terminals serving as corresponding first and second input terminals of the differential amplifier, and an output terminal at which an amplified signal is output dependent on input signals received at the input terminals; bandgap voltage reference circuitry comprising the first input transistor and a third input transistor whose control terminals are connected together to form a reference terminal at which a bandgap voltage reference signal is generated as a first input signal; and a regulation stage connected to receive the amplified signal output from the differential amplifier and configured to generate a voltage-regulated signal based thereon, and connected to the second input terminal of the differential amplifier so that the second input signal is a feedback signal dependent on the voltage-regulated signal.
