Cara Merancang Amplifier

[gantex]

bisa kasih contoh simulasinya kang ?
ato bisa seperti ini, bener ngak yah :-?

.options plotwinsize=0
.options method=gear
.options numdgt=7
.param Freq=1K
.param numcyc=30
.param dlycyc=20
.param FFT=2**16
.param simtime=numcyc/Freq+dlytime
.param dlytime=dlycyc/Freq
.param timestep=(simtime-dlytime)/FFT
.four {Freq} V(Vin) V(Vout)
.four {Freq} 4 V(Vin) V(Vout)

.tran 0 {simtime} {dlytime} {timestep}

.option numdgt=15

.option reltol=1e-6
.option ptrantau=0
