推 deathcustom: Av = -gm*RD*/(sCL*RD+1), w_3dB = 1/RDCL 04/17 10:01
→ deathcustom: f_3dB = w_3dB/2pi = 1/(2.25e-9*2pi) = 70MHz 04/17 10:03
→ deathcustom: Attenuation = 20log(3G/70M) = 32.64 dB 04/17 10:04
→ deathcustom: 增益減少32.6dB 04/17 10:04

已知CS組態電路增益與Rd有關，想問各位大大要怎麼求出在3GHz時增益減少的比例?
解答提供的答案為減少2.27倍
