Explanation: The limitation of vertical pnp transistor is that, collector has to be held at a fixed negative potential, as substrate is to be held at the most negative potential in the circuit for providing good isolation. 8. Which method is used in the fabrication of pnp transistor?
A. Vertical substrate pnp
B. Triple diffused pnp
C. Lateral pnp
D. All of the mentioned
