Abstract
Close matching in the respective parameters of bipolar transistors fabricated on the same monolithic chip facilitates the design of a circuit characterised by where I0 is the output current, I1, ¿, Im are input currents and n (¿1) is an integral number. Experimental measurements for n=2, m=3 and 1 ¿A ¿ Ir ¿ 1 mA are presented and discussed in relation to a simple theoretical error formula.
