A circuit with only resistors and unity gain amplifiers can be proven to be
equivalent to the Ricketts and Kemeny electrical model of multiterminal qu
antum Hall effect (QHE) devices. By means of the new equivalent circuit, co
mmercial software for electronic circuit analysis can be used to study a QH
E measurement system. Moreover, it can be easily implemented, and we were a
ble to build a circuit that simulates the electrical behavior of a QHE devi
ce. Particular care was taken in the design to reduce the effect of parasit
ic capacitances, which act as loads connected to the device terminals. Boot
strap buffers have been adopted to significantly reduce the capacitance of
input stage. The small residual loading effect can be calculated and elimin
ated, allowing simulation of a QHE device with good accuracy. (C) 1999 Amer
