ABSTRACT:
A voltage-to-current converter for converting an input voltage signal into an output current signal, while providing a filtering function. The input voltage signal is converted to an intermediate current signal by an input resistance and an equivalent resistance provided by, for example, an inverting amplifier and a transistor. A current mirror having a dominant pole converts the intermediate current signal to the output voltage signal, and provides low pass filtering. The converter avoids the use of linear capacitors, and can be easily implemented in a CMOS device.
