WebHere are the most common mirror sizes for the different types of mirrors: Wall Mirror – 24 inches by 34 inches. Interior Closet Door Mirror – 18 inches by 36 inches. Vanity Table … WebNov 14, 2014 · A question on the current mirror. We are designing a circuit whose differetial pair needs the tail bias current of 16mA, which is mirrored from a 20uA PTAT current source. So the ratio of mirror is about 800. I have the concern the small mismatch will be amplified by the big ratio and leads to the big descrepancy of current.
