schematic shows that the integrating capacitor of the fi rst integrator, C
1
, is split into
three capacitors, namely C
11
, C
12
, and C
13
. Let us assume that the input signal comes
into the circuit through the M
1
C
1
path—that is, the SC circuit realizes a low-pass
lter. During the idle case (Φ
2
= 1), the op-amp’s output at node A is given by

Next, Φ

= 1, and the capacitor C
13
is discharged to ground while the stored charge
on C

is transferred to C
11
. Based on the charge reservation rule, we can write the
