Input Track-and-Hold (T/H) Circuits
Figure 3 displays a simplified functional diagram of the
input T/H circuits. In track mode, switches S1, S2a,
S2b, S4a, S4b, S5a, and S5b are closed. The fully dif-
ferential circuits sample the input signals onto the two
capacitors (C2a and C2b) through switches S4a and
S4b. S2a and S2b set the common mode for the ampli-
fier input, and open simultaneously with S1, sampling
the input waveform. Switches S4a, S4b, S5a, and S5b
are then opened before switches S3a and S3b connect
capacitors C1a and C1b to the output of the amplifier
and switch S4c is closed. The resulting differential volt-
ages are held on capacitors C2a and C2b. The ampli-
fiers charge capacitors C1a and C1b to the same
