The circuit is remarkably immune to HF
R
FI provided that
certain design rules be adhered to:
1. Use SMT components.
2. Always use a ground plane under the circuit.
3. Use a 0.1uF bypass cap very close to the supply pins.
4. If ESD diodes are used, always use
R
e1,
R
e2, and Cf.
Make
R
e1 /
R
e2 as large as possible without
compromising gain (depends on Cf and Cx).
5. Keep all ESD components close to the IC.
6. Do not route the sense wire near other traces or wires
7. The sense electrode should be kept away from other
conductors, even ground, which can re-radiate in
R
F
currents.
8. If the ESD diodes are not used, use
R
e1 in the electrode
trace anyway, with a value as large as possible without
compromising gain.
Cf acts to shunt aside
R
F from entering the two diodes, thus
preventing their conduction due to
R
F currents. This form of
conduction will lead to false or erratic operation. Cf also acts
to lower sensitivity, and in many cases Cs will need to be
increased to compensate for this loss.
