Q 14.20)

Following the method of Example 14.6 and combining equations (14.88-14.90), the output

offset is given by:

To minimize charge injections we take L = Lmin = 0.18m. We can then solve for the device

width W required to maintain a certain de offset:

Rounding to w=8m, we can find the resulting switch on resistance:

The settling time of C2 is given by 5 RC time constants of:

Q 14.21)

For a settling time of 40ns, we require the switch on resistance to satisfy:

The switch effective gate-source voltage is:

To minimize charge injection, take L = Lmin = 0.18m. We can then solve for the device width:

By combining equations (14.88 – 14.90), we can calculate the dc offset:
