ngspice

ngspice simulation tutorial and template skill. Provides nine standard simulation examples: (1) Transient — RC charging voltage and current; (2) DC — NMOS Id-Vds family curves; (3) AC — RC low-pass filter frequency response; (4) Noise — RC filter output noise spectral density and kT/C; (5) Transient — sample-and-hold switch comparison; (6) Transient — kT/C noise time-domain statistical measurement; (7) DC — NMOS current mirror output characteristics; (8) AC — common-source amplifier frequency response; (9) DC — transmission gate on-resistance. Built-in PTM 180/45/22nm models included.
