The current gain below the specified value of the input current is close to one. By suitably choosing certain of the circuit parameters, the circuit operates in a substantially temperature-independent manner.ROBERT A. BLAUSCHILD
This circuit takes an input and provides two outputs equal to the input, but with opposite phases. The capacitor and the 150k and 56k resistorsbiasthe transistor. The base-emitter junction acts like a diode, so that the emitter will be a diode drop lower than the base. The emitter voltage...
The buffers can be a pair of JFET op amps or two electrometers with unity-gain outputs. 该缓冲器可以是一对JFET运算放大器或者是两个具有单位增益输出的静电计。 www.eefocus.com 2. The use of the snubber CIRCUIT is usually recommended for unity gain configurations. 单位增益配置时通常推荐使用缓冲...
The unity-gain bandwidth for a component or amplifier circuit can be determined from frequency sweep simulations with the amplifier operating in the linear regime. This requires using a SPICE model for your amplifier and other components in your circuit. Simply sweep the source frequency in your ci...
