Abstract

PURPOSE:To obtain a sawtooth wave generator where the linearity is not degraded even if an external signal is superposed, by constituting amplifiers operating as a Miller integrator in two stages. CONSTITUTION:When a DC power is applied to a power supply terminal 11 and a horizontal driving pulse (a) is applied to a terminal 10, amplifiers 14 and 16 constitute a Miller integrator together with a capacitor 2 and a resistance 3, and sawtooth wave voltages (b) and (c) are generated in an output terminal 9. Next, when an external signal which is a part of a vertical deflecting voltage (d) is applied to a terminal 7, an output (e) is obtained in the output terminal 9. Consequently, since a sawtooth wave voltage for horizontal deflection which is a main signal is generated by the Miller integration due to amplifiers 14 and 16, the linearity is not degraded, and a saw tooth wave voltage of a good linearity is obtained.
