Active inductor symbolic analysis

Enhanced analytical equations are derived to predict the inductance and series resistance of a common active inductor configuration. The equations, based on MOSFET small-signal parameters, are used to predict the inductance and series resistance of an active inductor implemented in a 0.18 ¿m CMOS process. The inductor's characteristics are presented, demonstrating analytical equation accuracy and circuit functionality between 70 MHz and 700 MHz.
