Abstract
Apparatus and methods provide a differential current buffer. The current buffer has cross-coupled feedback and offers relatively good common-mode rejection and a relatively low and linear input impedance, which can reduce intermodulation distortion. The current buffer can be used in, for example, an RF modulator, such as a quadrature modulator.
