It can be seen that this is identical to Equation (3.49). Thus, this LDI also has a
phase shift of p/2.
To investigate the behavior of the series SC integrator with respect to C
p3
(i.e., the
only parasitic capacitance that matters), we again employ the principle of superposi-
tion. The circuit shown in Figure 3.2(d) is essentially composed of two subcircuits:
an ideal series SC integrator with a switched capacitor of Cand an ideal parallel SC
integrator with a switched capacitor of C
p3
. Note that the outputs of both circuits
jump only when Φ
1
→1. From Equations (3.41) and (3.52) we can obtain the t ...
