Design a two stage operational transconductance amplifier (OTA) to meet following specifications:

$A_v > 4000 V/V$, $V_{DD} = 2.5 V$, $V_{SS} = -2.5 V$, $GBW = 6 MHz$, $C_L = 10pF$, $SR > 10 V/ \mu s$, $60^0$ phase margin, $-2 V ≤ V_{out} range ≤ 2V$, $ICMR = -1.125V to 2V$, $P_{diss} ≤ 2.5 mW$. Use $K_n = 110$, $\mu A/V^2$, $Kp = 50 \mu A/V^2$, $V_{Tn} = | V_{TP} | = 0.7 V$, $\lambda_N = 0.04 V^{-1}$, $\lambda_P = 0.05 V^{-1}$, $Cox = 2.47 fF/ \mu m^2$.

Verify that the designed circuit meets required voltage gain or power dissipation specifications.
