Multiple choice

In the CMOS inverter circuit shown, if the transconductance parameters of the NMOS and PMOS transistor are kn = kp = $\mu$nC0x $\frac{W_n}{L_n}$=$\mu$p Cox $\frac{W_p}{L_p}$= 40 $\mu$A/ V2 and their threshold voltage are VTHn = |VTHp| = 1V, the current I is

  1. 0 A

  2. 25 $\mu$A
  3. 45 $\mu$A
  4. 90 $\mu$A
