三极管电路现在虽然用的不多, 但也是不可缺少. 分享一下大家的经验, 大家常用哪些三极管作为:

1. VIDEO放大电路, VIDEO BUFFER

2. AUDIO放大电路, AUDIO BUFFER

3. 逻辑电路

..............................

如何选用三计管? 如何设计相应的电路?

2)如何选TRANSISTOR?

http://www.americanmicrosemi.com/tutorials/bipolartransistor.htm

Primary considerations when selecting a transistor are:
(a) Voltage ratings of all three junctions
(b) Power rating and thermal resistance
(c) Current handling capability and the transistor case size
(d) Leakage currents, mainly Icbo and Iebo
(e) Frequency response and /or switching times.
(f) Current gain (HFE and hfe)
(g) Temperature parameter variation.
(h) Saturation resistance
(I) h-parameters for linear applications

3) BC857, BC847可用
