Abstract: An integrated circuit includes at least one differential pair of transistors, a bias current generator that is configured to generate a bias current on a bias node that is coupled to a source terminal of each transistor of said differential pair by a respective resistive element. A compensation current generator is configured to generate a compensation current in one of the two resistive elements so as to compensate for a difference between actual values of the threshold voltages of the transistors of said differential pair.

Abstract: A method for controlling operation of a comparator that includes an amplifier that is connected at an input of the comparator includes neutralizing any change of state of a signal output by the comparator starting from each moment in time at which the change of state of the output signal occurs and lasting for a duration of propagation to compensate for a duration of propagation of signals within the amplifier.

Abstract: A calibration method of a temperature sensor is provided. The temperature sensor having a current source and a ring oscillator generating a square pulse signal with a temperature-dependent square pulse frequency. The acquisition of a first square pulse frequency measurement at a first temperature from the square pulse signal forms a first measurement point. A second square pulse frequency measurement at a second temperature from the second square pulse signal forms a second measurement point. The determination of the relation data being representative of an affine relation between square pulse frequency measurements and temperatures. The affine relation being defined by a used proportionality coefficient modified with respect to a measured proportionality coefficient of a measured affine relation linking the first measurement point and the second measurement point.

Abstract: An operational amplifier integrated circuit includes a differential pair of transistors having a first input, a second input. A bias current generator applies a bias current to an output of the differential pair of transistors. A control loop generates a control voltage arising from a difference in potentials between the first input and the second input. An additional current that is added to the bias current is generated in response to the control voltage.

Abstract: A comparison circuit includes an input interface configured to receive input signals and an output interface configured to deliver an output signal. A comparator is coupled between the input interface and the output interface. An amplifier is coupled between the input interface and the comparator. A neutralization circuit is configured to neutralize any change of state of the output signal starting from each moment in time at which the change of state of the output signal occurs and lasting for a second duration of propagation that compensates for a duration of propagation of signals within the amplifier.

Abstract: Series of first ramps and second ramps are generated. A circuit delivers a first signal representative of the comparison of each first ramp with a set point and delivers a second signal representative of the comparison of each second ramp with the set point. Based on the first and second signals: a first ramp is stopped and a second ramp is started when the first ramp reaches the set point, and a second ramp is stopped and a first ramp is started when the second ramp reaches the set point. The value of the set point is modulated in response a maximum value of the first/second last ramp compared with the set point.
