Układ elektroniczny cyfrowego syntezatora konduktancji do symulacji dużych rezystancji

The paper describes the electronic circuit for digital controlled conductance synthesis including monolithic amplifies and monolithic digital-analogue converter. On fig. 3 it is shown the electronic schematic of this digital controlled conductance synthesizer. It was formulated equations as the characteristic description of this synthesizer. The experimental examination results of synthesizer model for resistance at the range from 10 MΩ to 1000 MΩ are described. The elaborated electronic circuit of resistance synthesizer have good qualities of resistance characteristic accuracy. The errors are better than 0,3% for simulation the resistance from 10 MΩ to 100 MΩ and errors are better than 1% for simulation the resistance to 1000 MΩ.
