  • Voltage to current converter with minimal noise sensitivity
    Patent number: 6058033
    Abstract: A voltage to current (V-I) converter includes a low pass filter, a first converting element, a second converting element, and an output. The low pass filter receives an input voltage signal and outputs a filtered voltage signal. The output of the low pass filter is fed to the first converting element, which converts the filtered voltage signal into a corresponding output current which is fed to the output of the V-I converter. Preferably, the voltage to current gain of the first converting element is high. The low pass filter and the first converting element form a low frequency or DC signal path. The V-I converter further includes a second converting element, which receives the input voltage signal and converts it into a corresponding output current which is also fed to the output of the V-I converter. This current is combined with the output current from the first converting element to produce an overall output current.
