Design of the Two-Stage, Open-Loop Comparator for a Slewing Response



Assume the specifications of provided figure are given below.



$$

\begin{array}{lll}

t_p=50 \mathrm{~ns} & V_{O H}=2 \mathrm{~V} & V_{O L}=-2 \mathrm{~V} \\

\mathrm{~V}_{D D}=2.5 \mathrm{~V} & V_{S S}=-2.5 \mathrm{~V} & C_{I I}=5 \mathrm{pF} \\

V_{\mathrm{in}}(\min )=1 \mathrm{mV} & V_{i c m}^{+}=2 \mathrm{~V} & V_{i c m}^{-}=-1.25 \mathrm{~V}

\end{array}

$$





Design a two-stage, open-loop comparator using the circuit of Fig. 8.2-3 to the above specifications and assume all channel lengths are to be $1 \mu \mathrm{~m}$.
