摘要： The disclosure provides a phase locked loop, PLL, for phase locking an output signal to a reference signal. The PLL comprises a reference path providing the reference signal to a first input of a phase detector, a feedback loop providing the output signal of the PLL as a feedback signal to a second input of the phase detector, a controllable oscillator generating the output signal based on at least a phase difference between reference and feedback signal, a digital-to-time converter, DTC, delaying a signal that is provided at one of the first and second input, a delay calculation path for calculating a DTC delay value. The PLL further comprises a randomization unit for generating and adding a stream of pseudo-random offsets, i.e. pseudo-random numbers, to the delay value. The offset is such that the target output of the phase detector remains substantially unchanged.

摘要： Described herein is a multi-channel biopotential signal acquisition system (900) in which a plurality of biopotential channels is corrected for common-mode interference. Each biopotential channel comprises an electrode (910, 920, 930, 940) for providing a biopotential input signal and an associated amplifier (950, 960, 970, 980) for amplifying the biopotential input signal and for providing a biopotential output signal (955, 965, 975, 985) that is processed in a processor (250, 260, 270, 990). Each biopotential output signal (955, 965, 975, 985) is passed to a common-mode feedback system (810) that determines an average common-mode signal and feeds that signal back to each of the amplifiers (950, 960, 970, 980) in each of the biopotential channels to enhance common-mode rejection ratio of the system (900).
