Explanation: The presence of Parasitic Capacitance at the isolating PN-junction, results in an inevitable capacitor coupling between the component and substrate. This also limits the performance of circuit at high frequencies. 2. Which isolation technique is used in applications like military and aeroscope?
A. Thin film isolation
B. PN-junction isolation
C. Barrier isolation
D. Dielectric isolation
Answer:A

A. Thin film isolation B. PN-junction isolation C. Barrier isolation D. Dielectric isolation
Explanation: In dielectric isolation a layer of solid dielectric is used for isolation purpose. This layer is thick enough such that its associated capacitance is negligible. Moreover, it is more expensive, which is justified by its superior performance. 3. Pick out the incorrect statement
