摘要： The circuit comprises an amplitude limiter made up with the use of two CMOS transistors and a circuit connected to the output of the amplitude limiter for filtering the signal and changing its level. The filtering and level-changing circuit is arranged, in particular, to achieve band-pass filtering in order to prevent aliasing effects which might arise during the sampling of the signal by subsequent switched-capacitance processing circuits, and to attenuate low-frequency components of the signal.

摘要： The device includes two channels for detecting and processing the signal provided by an accelerometric sensor, operating in two frequency bands in which peaks indicative of pinking (knocking) may occur. In each combustion phase, a third channel, also connected to the sensor, provides a signal representative of the noise component of the signal from the sensor, in a frequency band in which the peaks do not occur. The signals provided by the first and second channels are integrated and then compared with a reference signal generated in dependence on the noise component detected cylinder by cylinder. The device thus enables pinking to be detected cylinder by cylinder.

摘要： A switched-capacitor circuit is described, which performs the functions of a full-wave rectifier and of an integrator and has a single operational amplifier and a comparator. The circuit is insensitive to the stray capacitances and offsets of the comparator and the operational amplifier. In particular, the input signal is sampled during only one phase of the clock which pilots the operation of the switched-capacitance network.

摘要： An automatic system for adjusting the output impedance of fast CMOS drivers, wherein the output impedance of a plurality of slaved drives is adjusted by a circuit for measuring and correcting mismatch between the output impedance of one of the drivers, taken as reference and dedicated for this purpose, and the impedance at the input of a reference transmission line, equal to the lines connected to the other drivers. The measuring of the output impedance of the reference drive is indirectly effected by inserting at the reference drive input a clock signal and by periodically measuring the output on the reference transmission line in correspondence with the positive half-period center. The measured voltage is sent to a comparator whereby it is compared with a reference level equal to half the maximum level present in the line under matching conditions and, according to the comparison result, a signal is supplied capable of charging or discharging a capacitor, across whose terminals a voltage controlling the driver output impedance is available.
