Crosspoint bias circuit arrangement |
摘要 |
A semiconductor transmission circuit arrangement which utilizes symmetrical transmission transistors and bias circuitry which exhibits a high output impedance and is arranged to maintain equal d.c. bias currents in the base and the emitter/collectors of the transmission transistor. A multiple collector transistor is utilized as a primary current source and a current mirror circuit is used as a control arrangement.
