13. Offset level : VOS
DC level of output signal is defined as follows.
14. Reset feed-through noise and peak reset feed-through noise : RFTN and PRFTN
RTFN is switching noise of φ R and φ CP. Reset feed-through noise (RFTN) and peak of RFTN (PRFTN) are
defined as follows.
<1> Bit clamp operation
2L1
φ R1
φ CP1
VOUT1
PRFTN
RFTN2
RFTN1
VOS
Caution This shows timing of VOUT1 side (φ2L1, φ R1, φCP1, VOUT1). The definition of VOUT2 side (φ2L2,
φ R2, φCP2, VOUT2) is equal.
<2> Line clamp operation
φ 2L1
φ R1
φ CP1 _"L"
VOUT1
PRFTN
RFTN1
VOS
Caution This shows timing of VOUT1 side (φ2L1, φ R1, φCP1, VOUT1). The definition of VOUT2 side (φ2L2,
φ R2, φCP2, VOUT2) is equal.
