Hi,
i have a problem with the op amp in the ahdlLib in Cadence.
I connected it as voltage follower with sinusoidal Vin+ (Amplitude 2.5V, f=10k), Vdd=5V.
I set the following parameters for the opamp:
gain=10000
frequ_unitygain=100M
rin=10M
vin_offset=0
ibias=0 (input current)
slew_rate=10M
rout=50
vsoft=4.9
iin_max=10m (maximum output current)
What i receive is a sinusoidal output signal with amplitude of around 1V. Why is the output amplitude much lower?
