摘要： A measurement circuit for providing the maximum and/or minimum voltage of a time-variant electrical input signal is presented. The measurement circuit contains a voltage reference unit to provide voltage reference signals and a comparator unit comprising multiple comparators. Each comparator receiving the electrical input signal at a first comparator input and a different voltage reference signal from the voltage reference unit at its second comparator input. The comparator unit provides comparator output signals based on said electrical input signal and said voltage reference signals. A logic unit receives the comparator output signals and provides a voltage output signal indicative of the maximum and/or minimum voltage of the electrical input signal based on the comparator output signals.The logic unit provides adaptation information to the voltage reference entity. The is adaptation information is dependent on the comparator output signals. The voltage reference unit adapts the voltage reference signals based on the adaption information.
