Abstract
A low voltage, current-folded signal modulator that reduces distortion in the output signal is provided. The signal modulator has a differential amplifier that receives a first input signal and converts it to a current, a current amplifier that has a low impedance input and provides an amplified current signal, and a differential pair circuit that receives a second input signal and modulates the amplified current signal by the second signal.
