SR = A(dvin/dt).

Here; dvo = sr*dt /vid =Acl.

Samantha said:   8 years ago
Closed loop gain Acl = SR/(dvi/dt).
= 5/(0.2/10ms),
= 250.

SLEW RATE = dV0/dt(MAX)= 5.

VOLTAGE GAIN = OUTPUT VOLTAGE / DIFFERENTIAL i/p VOLTAGE.

= 5/0.02.

= 250.

Thanks ajin!

Total effect = 0.2/10ms
=.02V/ms
So voltage gain= 5V/.02V/ms

Slew rate = 2piefv

Use

1. SR=(V(out)-V(in))/t

and

2. Gain=V(out)/V(in)
