* .ac oct 100 1k 100mega
* .dc V_BIT0 0 {VCC} 0.01
* Rb controls gate delay (rise and fall edge) as well as gate power consumption.\n \nRb=100 --> 4/5ns gate delay; 35mA gate power\nRb=200 --> 6/8ns gate delay; 20mA gate power
* This invertert chain produces 1.5V swing around 2.5V, consumes around 15mA per inverter and seems to have a propagation delay of about 1ns.
* I think this is the inverter I would want to use for logic. This needs a 5V supply to operate reasonable well though, which incerases power consumption quite a bit.
