In the circuit shown, the threshold voltages of the pMOS (|Vtp|) and nMOS (Vtn) transistors are both equal to 1 V. All the transistors have the same output resistance rds of 6 MΩ. The other parameters are listed below:
\({\mu _n}{C_{ox}} = 60\frac{{\mu A}}{{{V^2}}}\;\;;{\left( {\frac{W}{L}} \right)_{NMOS}} = 5\)
\({\mu _P}{C_{ox}} = 30\frac{{\mu A}}{{{V^2}}}\;\;;{\left( {\frac{W}{L}} \right)_{PMOS}} = 10\)
μn and μp are the carrier mobilities, and Cox is the oxide capacitance per unit area. Ignoring the effect of channel length modulation and body bias, the magnitude of the gain of the circuit is ____ (rounded off to 1 decimal place).
