Hello Everyone,
Need one help. I need to design a flip-around track and hold circuit in CMOS 0.18um technology with an input swing 0.2Vpp to 0.4Vpp from a generator with 50 ohm impedance and an accuracy of 10-bits. Sampling frequency is 10 M s/s.It needs to drive a load capacitance of 1pF.Can somebody please help me answer the following questions?
1. How do we choose the GBW and DC gain of the OP-AMP?
2. How do we determine the value of the hold capacitor?
3. What DC level should I choose at my input?
Any suggestions and pointers to relevant references will be a big help.
Thanks.
With Regards,
Anu Pillai.
