βnpn=99 , βpnp=49 , η=3.95,λ=1,Ege=1.143 V ,Vben=0.65V @ Ic=10 uA,Tn=300K
Vt=26mV @ 300K.
1---what is above circuit?
2---design above circuit such that IQ5=IQ6=100 uA ,Va=magic voltage@ T=Tn=300K, using equations calculate R2 & R1 for Va to be magic voltage.
3---calculate voltage Vout.
4---identify the startup circuit
5---design Rb such that Q4 turns off after start up.
thanks ,hr_rezaee and ambreesh,
this is a question in recruiting test . the circiut in attachment.
I guess η is γ,λ is α, in CMOS ANALOG CIRCUIT DESIGN ,second edition,P E.Allen ,(4.6-11),right??
