Design the nmos gain stage with a pmos current mirror load as shown in figure 1 with the following specifications
external capacitive load: 100 ff
slew rate: > 1 v/ns
dc differential gain: > 40 db
– 3 db bandwidth: > 10 mhz
amplitude of ac output voltage: > 0.8 v.
cmrr at low frequencies: > 80 db
for simplicity select vgs_n = 0.8 v for the nmos devices in the differential pair. vgs_p for the pmos in the current mirror can be selected in a broad range as long as the nmos devices in the differential pair operate in the saturation region.
b) for your design estimate the following parameters:
voltage range for common-mode input signal: vicm_max, vicm_min

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
