Good day EDA fellows,
The CDS technique appeared at Chapter 10 Section 7 of the Johns and Martin,page 433.
To quote the book, "A wide band amplifier that uses CDS, similar to the SC amplifier of Fig.10.31, but with superior high frequency operation, is shown in Fig. 10.34. During phi(Greek character)2, C(prime)1 and C(prime)2 are used to have
vout = -((Cprime1) / Cprime2)) x Vin
I really can't understand why the Vout is described as such during phi(2). It appeared to me that during phi(2), the vout is in a floating situation since the switch with phi(1) is open.
Shown below are the figures;
Figure 10.31:
Figure 10.34:
Thank you.
