摘要： A horizontal deflection output circuit, such as used in a TV receiver or a display device, includes a series circuit composed of a ringing preventing resistor and a one-way switching element connected in parallel with a linearity correcting coil. That one-way switching element is turned on at the beginning of a horizontal scanning period to feed a current to the ringing preventing resistor but is turned off in the vicinity of a fly-back period to block the flow of the current to the ringing preventing resistor. Thus, the power loss due to the current flowing through the ringing preventing resistor for the fly-back period can be reduced according to the present invention.

摘要： A cascode amplifier comprises a grounded-emitter drive transistor which has a collector supplied with a bias current from a bias current source and operates in response to an input signal and a grounded-base (or grounded-gate) output transistor which has a collector supplied with a bias current from a constant voltage source, wherein the collector of the drive transistor is connected to the emitter (or source) of the output transistor. A constant current circuit is connected to the junction between the collector of the drive transistor and the emitter (or source) of the output transistor for supplying a part of the bias current applied to the drive transistor to thereby decrease the bias current of the output transistor while causing the drive transistor to be operated in the linear region. The cascode amplifier is thus imparted with a broad band frequency characteristic.
