Q$1.[20$ pts$]$ For the ECL NOR$/$OR gate below, assume $V_{BE(FA)}=0\mathrm{.}75V,V_{BE(SAT)}=0\mathrm{.}8V,V_{CE(SAT)}=0\mathrm{.}2V,{}_F=49$ :

a$.[10$ pts$]$ Find all the critical voltages $($including $V_S),$ logic swing, and noise margins for NOR.

b$.[2$ pts$]$ Draw the VTC for NOR.

c$.[4$ pts$]$ Find the maximum fan$-$out for NOR. Assume the load gates have reduced $V_{OH}$ of the driving gate further down to $-0\mathrm{.}79$ V $.$

d$.[4$ pts$]$ Find the average power for NOR.
