Idealized operational amplifier with limitation

Description
Idealized operational amplifier with saturation:
- Input currents are zero.
- No-load amplification is high (but not infinite).
- Output voltage is limited between positive and negative supply.
Supply voltage is either defined by parameter Vps and Vns or by (optional) pins s_p and s_n.
In the first case the necessary power is drawn from an implicit internal supply, in the second case from the external supply.
