The major disadvantage of PN-junction isolation technique is,
A. Formation of Parasitic Resistance
B. Formation of Parasitic Capacitance
C. Formation of Isolation island
D. None of the mentioned
Answer:A
The major disadvantage of PN-junction isolation technique is,
A. Formation of Parasitic Resistance B. Formation of Parasitic Capacitance C. Formation of Isolation island D. None of the mentioned
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?
