Test... Ini hanya test... Ini contoh rancangan pre-amp transistor tegangan tinggi dalam bahasa modeling Netlist SPICE: - Code:
-
Nama sirkit: HV Pre-Amp With BC546A
* (Baris pertama adalah deskripsi singkat nama sirkit.)

* Berikut ini contoh detail netlist:
* Forward bias; net: bias & VCC, fixed-resistor 270k
Rbias_fwd bias VCC 270k
* Reverse bias; net: bias & 0, fixed-resistor 6.5k
Rbias_rev bias 0 6.5k
* Q1 Collector Load Media; net col_load & VCC, fixed-resistor 3.9k
Rcol_load col_load VCC 3.9k
* Static Feedback Control; net stat_fb & 0 (GND), fixed-resistor 82-ohms
Rstat_fb stat_fb 0 82
* Dielectric input couple; net v_in & bias, el. cap 10uF
Cf_in v_in bias 10u
* Dielectric output couple; net col_load & out, el. cap 10uF
Cf_out col_load out 10u
* Output final loader; net out & 0 (GND), fixed-resistor 3.9k
Rout_load out 0 3.9k
* Q1, BC546A, net: P1 = col_load (collector) P2 = bias (base)
* P3 = stat_fb (emitter)
Q1 col_load bias stat_fb BC546A
* DC source: DC 63 V, net VCC & 0 (GND)
Vsup VCC 0 dc 63
* Signal source: Freq. 1kHz, Mag. 0.7V, Offset = 0, Frame-Wave: Sinusoid
Vsrc v_in 0 dc 0 ac 0.7 sin(0 0.7 1000 0 0)
* Batch control, diawali perintah .control
.control
* Transient analysis: step=1000, stop=2ms, start=1ms max=2ms, nouic
TRAN 1000 2ms 1ms 2ms
* Jalankan perintah cek operating point (OP)
OP
* Jalankan simulasi (RUN)
RUN
* Tampilkan sinyal output pada GUI NGSPICE:
PLOT V(out)
* Akhir batch control berupa perintah .ends
.ends
* Akhir netlist berupa perintah .end
.end
Salin contoh netlist di atas dalam rupa file bernama "hv_pre_amp.cir". Jika Anda bekerja dengan komputer ber-sistem operasi GNU/Linux dan terinstalasi NGSPICE 2.1, Anda dapat jalankan Netlist SPICE di atas dengan perintah: - Code:
-
ngspice -a hv_pre_amp.cir
Selamat mencoba, Mohon maaf jika salah, ini hanya testing...  Berapa tegangan DC di net col_load? Ya... kira-kira 31.5V Berapa tegangan sinyal peak-to-peak di net out? Kira-kira 15Vpp
