Estimate the maximum allowed output voltage for the p-MOS current source when the current value and the differential output resistance remain nearly constant, e. g. the mosfet operates in the saturation region. The MOSFET is biased with the gate-to-source voltage 1.26 V (absolute value). The current source is powered from the DC voltage source VDD = +3 V. Assume the standard process parameters: Vtp = −0.8 V.
