(a)
From Eg. (7.71)
Rout = (1 + gm1ro1)1
gm2+ro1
(b)
From Eg (7.71)
Rout = (1 + gm1ro1)1
gm2+ro1
(c)
From Eg (7.71)
Rout = (1 + gm2ro2)(ro1|| 1
gm3) + ro2
(d)
From Eg. (7.71)
Rout = (1 + gm1ro1)(ro2|| 1
gm3) + ro1
(7.42)
Voltage gain, Av=GmRout,
where Gmand Routare the transconductance and output resistance
of the circuit respectively.
To find Gm:
1
