Explanation: When the op-amp has wide bandwidth, schottky noise is produced. The amount of schottky noise is greater with wider bandwidth and large resistance. 7. Mention a scheme to reduce the effect of electrical noise on ICs?
A. Isolating ICs on different boards
B. Add a filter near ICs
C. Physical shielding of ICs
D. Use of compensating networks near ICs

A. Isolating ICs on different boards B. Add a filter near ICs C. Physical shielding of ICs D. Use of compensating networks near ICs
Explanation: Physical shielding of the ICs and associated wiring helps to prevent external electromagnetic radiation from inducing noise into the internal circuitry. 8. Internal noise generation can be reduced by keeping
