Electronics 245 - Week 6 - Lecture 13

Describe the pnp transistor:

• Biases

• how it operates

• what it looks like

• What it does

• Current equations

Describe the circuit symbols and conventions for:

• pnp transistor

• npn transistor

• their currents

Draw the common base configuration of the npn and pnp transistors

For the common-base configuration of either npn or pnp transistor:

• Describe the currents

• Describe the voltages

• biases and operating modes

For the common-emitter configuration of either npn or pnp transistor:

• Describe the currents

• Describe the voltages

• biases and operating modes

Describe what is meant by the Early effect:

• Define early voltage

  • give its formula
