发明名称 IMPROVED OPERATIONAL AMPLIFIER OUTPUT STAGE
摘要 The present invention is directed to a buffer stage for buffering and isolating a signal source from an external load. The stage has a signal input terminal for receiving an input signal from said signal source and a signal output terminal for providing an output signal (OUTPUT), corresponding to said input signal (INPUT), to said external load. The stage comprises: an input section (102) including at least two driver transistors (Q3 and Q4) each arranged so as to operate with a predetermined bias current; an output section (106) including at least two output transistors (Q1 and Q2) each arranged so as to operate with a predetermined quiescent current a voltage source, coupled to the input and output sections and constructed and arranged so as to set the quiescent currents flowing through the output transistors (Q1 and Q2) substantially independent of the size of the bias current flowing through the driver transistors (Q3 and Q4).
