Reference Current of IC Amplifier Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reference Current = Output Current*(Aspect Ratio/Aspect Ratio 1)
I_ref = I_o*(WL/WL₁)
This formula uses 4 Variables

Variables Used

Reference Current - (Measured in Ampere) - A reference current is just a stable source of current that does not fluctuate over temperature, supply voltages or loads.
Output Current - (Measured in Ampere) - Output Current is the current the amplifier draws from the signal source.
Aspect Ratio - Aspect Ratio is the ratio of the width of the channel to the length of the channel.
Aspect Ratio 1 - Aspect ratio 1 is the ratio of the width of the channel to the length of the channel of a conductor 1 in the circuit.

STEP 1: Convert Input(s) to Base Unit

Output Current: 5 Milliampere --> 0.005 Ampere (Check conversion here)
