Switched capacitor integrators generally exhibit higher
input offsets than discrete R, C integrators. These offsets
are mainly due to the charge injection of the CMOS
switches into the integrating capacitors and they are
temperature independent.
The internal op amp offsets also add to the overall offset
budget and they are typically a couple of millivolts. Be-
cause of this, the DC output offsets of switched capacitor
filters are usually higher than the offsets of discrete active
filters.
Figure 24 shows half of an LTC1060 filter building block
with its equivalent input offsets VOS1, VOS2, VOS3. All three
are 100% tested for both sides of the LTC1060. VOS2 is
generally the larger offset. When the SA/B, Pin 6, of the
LTC1060 is shorted to the negative supply (i.e., mode 3),
the value of the VOS2 decreases. Additionally, with SA/B
low, a 20% to 30% noise reduction is observed. Mode 1
can still be achieved, if desired, by shorting the S1 pin to
the lowpass output (Figure 25).
