FIELD: electrical engineering.
SUBSTANCE: simulator has reference resistor, simulation range resistor, serial chain of N resistors of stairs, connected in parallel to range resistor, and switch. Chain of N resistor is connected in series with reference resistor. Current outputs of simulator have to be output of chain of N resistors and free output of reference resistor. Inputs of switch are connected to outputs of resistors of stairs. Simulation range resistor is connected in parallel to chain of N resistors of stairs. Free output of reference resistor has to be potential output of simulator. The other potential output of simulator has to be output of switch.
EFFECT: 150 times reduced error of simulation of increment of resistance.
