Homework Statement
The circuit above shows a simple transistor amplifier with the given data:
β=100, VA = 100V, RL = 10kΩ
a) neglect the "early-effect" and design the circuit so that IE = 0.5mA and VC = 5V.
Homework Equations
The Attempt at a Solution
I'm familiar with the β part, it means DC gain, or collector current divided by base current. What I'm not familiar with is VA. Where is VA measured? If it's a typo, what can it be? I would ask my professor this, but he's away for the week so that makes it slightly difficult.
More to the problem itself. The DC analysis here should be very straight forward, I feel I just need some help to get started.
I need to set up an equation here so that IE = 0.5mA and VC = 5V. Do I also need to analyse the base-to-collector "junction" to see if it's a forward or reverse biased pn junction? That way I get the base-to-collector voltage (VBC)
Pardon me if I'm far off here, but I'm looking at a slightly different circuit for DC analysis.
Any help of guidance here will be greatly appreciated, thanks.
