Abstract
Hybrid differential pairs and methods of their hybridization by connecting and operating in parallel a degenerated differential pair with a multitanh. Proper matching of the degenerated differential pair and the multitanh results in higher linearity levels than can be attained with either approach individually. Also, the hybrid benefits from reduced process variation when compared with prior multitanh solutions. Increased gain, increased linearity, reduced noise and reduced supply current can all be achieved in a manufacturable fashion using the invention.
