ONLY LTSPICE SOLUTION!!!!!!!!!!!!!!!$11$ Design a basic NMOS differential amplifier circuit using MOSFETs, at LTSPICE which includes $($give me LTSPICE solution$)$

$-$A current mirror as the active load.

$-$A tail current source for biasing the differential pair.

$-$VDD$,$tail current, and input signal amplitude and frequency are $\backslash (1\mathrm{.}8\backslash$mathrm$\{$~V$\},1\backslash$mathrm$\{$~mA$\}\backslash ),$and $0\mathrm{.}1$mVpp $($Sinusoidal$)$and $10$kHz$.$

Choose transistor dimensions $($W$/$L ratios$)$to ensure proper operation in the saturation region. Select resistor or current source values to set the desired bias current.

@ DC operation:

Simulate the DC operating point to verify that the transistors are operating in the correct regions.

@AC operation:

Perform a small$-$signal AC analysis to determine:

$-$Differential gain $($Ad$),$Common$-$mode gain $($Acm$),$Bandwidth $(3$dB and unity$-$gain$)$

$-$Input impedance $($Zin$).$

$-$Output impedance $($Zout$)$

CMRR Calculation

Simulate the common$-$mode gain by applying the same input signal to both inputs

Calculate the CMRR$=20$log$($Ad$/$Acm$)$where Ad is the differential gain and Acm is the common$-$mode gain.

NOT!! Aim for a high differential gain $($Ad$>80[$V$/$V$]).$Ensure CMRR is greater than $60$dB $.$Minimize power consumption.
