Open the CIPO recordAbstract From the Canadian patent
A wide bandwidth, low power dissipation cascode video output amplifier suitable for driving an in-line gun color picture tube or the like. The cascode amplifier includes a low voltage, small signal common, emitter amplifier transistor and a high voltage common base transistor. An active load circuit comprising a transistor of like conductivity with respect to the common base and common emitter transistors is coupled between the collector of the common base stage and a source of operating voltage. A disconnect diode inter-, posed between the emitter of the load transistor and the collector of the common base transistor is biased to a, non-conductive state under quiescent conditions. Voltage …
