摘要： A relaxation oscillator of reduced complexity is described which can be constructed as part of a silicon integrated circuit. The current controlled oscillator includes complementary field effect transistors operating in enhancement mode. The drain of one FET is connected to the gate of the other FET and vice versa. The resulting CMOS circuit functions as a four-layer diode. A resistor is connected between the drains of both transistors. A storage capacitor is connected between the sources of both transistors. A current source is connected to charge the storage capacitor such that the frequency of an oscillator output signal is determined by the current generated by the current source.

摘要： The current which passes through the vertical deflector of a transistorized color television receiver is produced by a circuit comprising an active switch controlled and modulated at the line frequency and supplied by line retrace pulses delivered by the secondary winding of a line transformer. The voltage at the terminals of an assembly compring a capacitor in series with the vertical deflector has a constant sign which is independent of the current passing through the deflector. The same secondary winding of the line transformer supplies both the vertical scanning circuit and a rectifier circuit for producing a d.c. voltage, in particular for the supply of video amplifiers.

摘要： The invention is concerned with a circuit arrangement for driving a saw-tooth current in a coil primarily intended for use as a line output stage for a television receiver. The circuit arrangement comprises a parallel resonant circuit which incorporates a line deflection coil, a diode connected in parallel with the coil to conduct the deflection current during a first portion of each operating cycle, a second diode and a thyristor connected in series with one another in parallel with the coil, the thyristor being fired by pilot pulses to conduct the deflection current in a second portion of each cycle immediately following the first portion, a series resonant circuit including a capacitor connected in parallel with a thyristor for quenching the thyristor at the end of the second portion of each cycle and a third diode connected in series with the capacitor in a circuit branch connected in parallel with the second diode and serving to transfer energy from the series resonant to the parallel resonant circuit. The circuit offers the advantage that it may readily be adapted to permit modulation of the deflection current and to provide auxiliary voltages unaffected by such modulation.

摘要： To permit use of a circuit in which the energy derived during horizontal flyback is used to control vertical deflection, without damage to the vertical deflection system upon vertical flyback, the vertical deflection output stage is dimensioned to have a time constant which is less, preferably about half, of the time constant of the sawtooth wave generator controlling vertical deflection. The vertical deflection output stage forms, in essence, a parallel oscillatory circuit which, to provide the lesser time constant, is damped.

摘要： A circuit arrangement for obtaining a periodic sawtooth current in a coil, particularly in a deflection coil of a kinescope, is described. The circuit arrangement comprises a first, unidirectional conductivity device, disposed in parallel to a circuit branch comprising the deflection coil, and a second, controllable switching device, having a control electrode connected to a source of periodic pulses which render conductive the second device during a part of the period of the sawtooth. The main feature of the circuit arrangement is to comprise a resonant series circuit disposed in parallel to the second device; the second device and the resonant series circuit are connected to the deflection coil and to the first device at least through a third, unidirectional conductivity device.

摘要： A capacitor is coupled to a vertical deflection winding for forming a resonant circuit therewith during retrace. A switched mode vertical deflection amplifier generates trace current in the deflection winding. A feedback resistor samples the current in the deflection winding and provides a feedback voltage to the amplifier. In order to substantially diminish a ringing component of the trace current at the beginning of trace, a cancellation circuit provides the amplifier with a voltage which cancels the feedback voltage during at least the latter portion of retrace.
