Change in Drain Resistance in MOSFET Formulas

Change in Drain Resistance is a measure when the two drain resistances exhibit a mismatch, as they inevitably do, the common-mode voltages at the two drains will no longer be equal. And is denoted by ΔR_D. Change in Drain Resistance is usually measured using the Kilohm for Electric Resistance. Note that the value of Change in Drain Resistance is always negative.
