摘要： A ramp generator is provided that includes an amplifier, first and second transistors, a variable resistive load having a control electrode, and a capacitor. The amplifier has an inverting input that receives a first reference voltage, and an output connected to the gate of the first transistor. The first transistor has a source connected to a second reference voltage, and a drain connected to the non-inverting input of the amplifier and also to the variable resistive load. The second transistor mirrors the current of the first transistor so as to charge the capacitor, which is periodically discharged by a discharging circuit. In one embodiment, the generator further comprises a comparator, a filter, and an integrator that control the variable resistive load so as to generate a slope having characteristics that are noticeably independent from dispersion, from manufacturing methods, and temperature.

摘要： The device for the comparison of the levels of two input signals MI, PI includes a first comparator COMP1, the switching of the comparator being expressed by a change-over of the output OUT1 of the comparator from a first logic state into a second logic state, the change-over of the output OUT1 from one logic state “0” into the other state “1” being faster than the change-over in the other direction. The device also includes a second comparator COMP2 with an identical structure, to whose input the signals to be compared are applied invertedly so that the switching operations in the comparators are inverted. The output of each comparator is applied to an associated logic circuit 1, 2 capable of accelerating the inverse switching in the other comparator for a change in the output corresponding to the fastest change-over.

摘要： A device for comparing two input signals includes a first comparator with differential outputs to whose inputs the signals are applied. The first comparator is followed by a second comparator delivering an output logic signal of the device. Each comparator includes at least one input differential stage, and each stage has two arms biased by a bias current generator. The comparison device may also include at least one additional current supply circuit associated with an arm of the input differential stage of the first comparator to copy the current of the arm and add it, with a multiplier factor, to the bias current of the input differential stage of the second comparator. This facilitates a corresponding switch-over.
