  • There are three fundamental bias currents to be chosen for this novel transimpedance stage: the collector current of the emitter followers Q8 and Q9, that of the common-emitter transistors Q10 and Q11, and finally the current in the folded cascodes formed by Q14 and Q15. Needless to say, the collector current of complementary pairs (e.g., Q8 and Q9) should be set to approximately equal values. There are various trade-offs associated with the selection of these bias conditions. Detailed… CONTINUE READING
