What is BiCMOS technology? List its advantages. 集成电路代考
- Briefly describe the process flow that uses an n-epitaxial layer, n+-buried layer and p-buried layer in the construction of a twin-well BiCMOS structure shown in Figure 1.
Figure 1
- Draw the conventional R-type and N-type BiCMOS inverters and briefly explain their drawbacks.
- The basic BiCMOS inverter circuit shown in Figure 2 uses a resistive shunt bipolar driver configuration. Describe the operation of the circuit by considering the case of VIN = low and the case of VIN = high. Discuss also the switching that occurs amongst the transistors for the circuit to arrive at the expected output voltage level. Determine if the circuit permits full logic swing at its output. 集成电路代考
