Biasing?

时间:04-10 整理:3721RD 点击:
I am in a puzzle of biaing a transistor.
Maximum collector-to-emitter voltage (VCEO) is given 12V max.
The device s parameters r available at the bias voltage of VCE 10V.
So if i choose the same bias voltage, will it be safe operating point?
I hv seen Japanese hv designed low noise preamplifiers with the transistor around VCE= 6V.

Hi

Yes if you use small signal S-parameters there will be no problem. But you can calculate how large your voltage swing will be at the collector. You can apply a voltage at the input and simlating the power at your load, you can calculate your voltage swing. Use the real part of the input impedance when you "look" towards your load from the collector.
