Abstract :
Two voltage buffers realized with discrete components are presented which provide very low input capacitance and input bias current, high-frequency capability and low-output resistance. This performance means they are well suited for employment in the characterization of operational amplifiers and specifically CMOS transconductance operational amplifiers
