Detailed Description
Theory of Operation
The HI5762 is a dual 10-bit fully differential sampling pipeline
A/D converter with digital error correction logic. Figure 15
depicts the circuit for the front end differential-in-differential-
out sample-and-hold (S/H) amplifiers. The switches are
controlled by an internal sampling clock which is a non-
overlapping two phase signal
, Φ
1
and
Φ
2
, derived from the
master sampling clock. During the sampling phase,
Φ
1
, the
input signal is applied to the sampling capacitors, C
S
. At the
same time the holding capacitors, C
H
, are discharged to
analog ground. At the falling edge of
Φ
1
the input signal is
sampled on the bottom plates of the sampling capacitors. In
the next clock phase,
Φ
2
, the two bottom plates of the
sampling capacitors are connected together and the holding
capacitors are switched to the op amp output nodes. The
charge then redistributes between C
S
and C
H
completing one
sample-and-hold cycle. The front end sample-and-hold output
is a fully-differential, sampled-data representation of the
analog input. The circuit not only performs the sample-and-
hold function but will also convert a single-ended input to a
fully-differential output for the converter core. During the
sampling phase, the I/Q
IN
pins see only the on-resistance of a
switch and C
S
. The relatively small values of these
components result in a typical full power input bandwidth of
250MHz for the converter.
