ABSTRACT:
A variable gain amplifier includes a voltage-to-current converter for converting the input voltage to a current, a current amplifier for amplifying the current converted by the voltage-to-current converter, a current-to-voltage converter for converting the current amplified by the current amplifier into a voltage, and a controller for controlling an amplification factor of the current amplifier.
