Abstract
The device comprises a synchronization unit, a sawtooth voltage former, a sawtooth voltage amplitude corrector and a comparator where the sawtooth voltage former by the inverting and non-inverting amplifier inputs is shaped where through resistor fixed voltages are supplied and a capacitor and a transistor switch are connected in parallel between inverting input and output, the base being connected with synchronization unit output through a resistive divider and a sawtooth voltage former output is connected with the comparator and the sawtooth voltage amplitude corrector, the output being connected to an inverting amplifier input through a resistor.
