Abstract:
A triangular-voltage generator has an input terminal that receives a power supply voltage and an output terminal that supplies a triangular-wave voltage having a repetition period. An operational amplifier in an integrator configuration has a first input, a second input and an output coupled to the output terminal. The second input receives a reference voltage as a function of the power supply voltage. The first input is selectively and alternately connected to the input terminal during a first half-period of the repetition period and to a reference terminal during a second half-period of the repetition period.
