fmin—— fmin>1/stop time fmax—— 这个值越大越准确,但会让仿真时间变长(之前看到有帖子用fmax=fclk,我认为是不对的啊,噪声是在无穷的频带积分的——虽然因为电路自带滤波会让远处的噪声被滤掉,但fmax取大一点会更精确)这个多试几次就知道哪个值合适了。 这里我也是按仿真kT/C noise的经验,各位大神能否...
Theoretical estimates indicate that the device structure described is capable of achieving fmax values in excess of 10 GHz. Present experimental devices typically have an fmax approximately equal to 3 GHz with a unilateral power gain of 7–8 dB and noise figure of 4 dB at 1 GHz. This ...
