Abstract
Techniques for providing a switchable inductor network having configurable inductance in response to a control signal. The switchable inductor network may adopt a fully symmetric architecture to reduce the effects of parasitic elements in differential mode operation. The switchable inductor network is particularly suitable for multi-mode communications circuitry applications, e.g., in the design of a voltage-controlled oscillator (VCO) or an amplifier or buffer in such circuitry.
