Abstract:
A circuit for generating first and second triangular waveforms opposite in phase to each other, the circuit comprising:a first capacitor having a first plate coupled to a first output at which the first triangular waveform is produced and a second plate coupled to a second output at which the second triangular waveform is produced;a first switch coupled between the first plate of the first capacitor and a first voltage reference and having a control terminal;a second switch coupled between the second plate of the first capacitor and the first voltage reference and having a control terminal; anda controller having a first output coupled to the control terminal of the first switch and a second output coupled to the control terminal of the second switch, the controller being structured to produce first and second control signals at said first and second outputs, respectively, in opposition to each other and thereby control the first and second switches in opposition to each other.
