Abstract :
The interconnection of a monolithic matched-f.e.t. pair and a high-frequency bipolar-transistor array permits the design of a fast high-input-impedance unity-gain buffer stage that does not employ passive components. Typical performance data are: input direct bias current <50 pA, output impedance <50 ¿, power consumption <60 mW.
