1. What is Miller capacitance? What is its role in High frequency amplifier design? Label all the involved variables in the Figure below and derive an expression for the Miller effect capacitances (input and output).
2. Explain why parasitic and internal capacitors (CWi, CWo, Cce, Cbe, Cbc) occur at high frequencies for BJT amplifier circuits.
3. Explain Why Differential amplifier using OpAmps are used in Medical devices and high precision instrumentation circuits
