| 摘要 |
In an electronic circuit supplied from supply terminals, a terminal in the circuit being biased to a voltage between the supply terminal voltages, connections from power supply terminals are made via current generator means. The circuit is preferably an RF, balanced and/or oscillator circuit. The current generator means are preferably controllable current generators, preferably controlled by an AGC, or a common mode or differential voltage control circuit. Preferably, the controllable current generators comprise a FET or are substantially constituted by each one MOS-FET. balanced, common-base, low-voltage Pierce crystal oscillator with two transistors and four to six current generator means is disclosed.
