* Reversed input polarity to fix output swing direction
V2 in N006 SIN(0 15m 1k) AC -1
V3 N003 N007 SIN(0 15m 1k) AC 1
* Note. You can change this as input / testcase

* ======================= SIMULATION CONTROL ========================

* Estimated total power
.print tran "Estimated total power :" (1u+51u+170u+30u)*v(N001)

* === AC ANALYSIS ===
