Abstract
A circuit for applications such as electrical impedance tomography includes a voltage-to-current converter having an input for receiving a voltage waveform and an output for outputting a current waveform to a load at an output resistance for the voltage-to-current converter. The voltage-to-current converter includes resistance control means for adjusting the output resistance of the voltage-to-current converter under computer control. The circuit of the present invention also includes an inductance control circuit operatively connected to the voltage-to-current converter for synthesizing a selected inductance. The inductance control circuit includes inductance control means for adjusting the value of the selected inductance by computer control. The operative connection between the voltage-to-current converter and the inductance control circuit causes application of the selected inductance to the output of the voltage-to-current converter so that an overall output impedance of the current source at the load is both high and controllable.
