摘要 |
A transconductor stage for high-frequency filters operated on a low voltage supply, being of a type which comprises an input circuit portion having signal inputs, further comprises a pair of interconnected differential cells (2,3) being associated each with a corresponding signal input. Each cell incorporates at least one pair of bipolar transistors (Q1,Q2;Q3,Q4) having at least one corresponding terminal thereof (e.g. the emitter terminal) connected in common.
