Adjustable differential inductor

A radio frequency integrated circuit (RFIC) comprises:

• a low noise amplifier operably coupled to amplify inbound radio frequency (RF) signals to produce amplified RF signals;
• a down conversion module operably coupled to convert the amplified inbound RF signals into low intermediate frequency (IF) inbound signals based on a receiver local oscillation;
• analog to digital conversion module operably coupled to convert the low IF inbound signals into inbound low IF digital signals;
• processing module operably coupled to convert the inbound low IF digital signals into inbound data and to convert outbound data into outbound low IF digital signals;
• digital to analog conversion module operably coupled to convert the outbound low IF digital signals into outbound low IF signals;
• up conversion module operably coupled to convert the outbound low IF signals into outbound RF signals based on a transmitter local oscillation;
• power amplifier operably coupled to amplify the outbound RF signals;
• and
• a local oscillation module operably coupled to produce the receiver local oscillation and the transmitter local oscillation, wherein at least one of the low noise amplifier, the down conversion module, the up conversion module, and the power amplifier include an adjustable differential inductor that includes:
• a first winding section;
• a second winding section;
• a third winding section;
• a fourth winding section;
• and
• a switching network operably coupled to configure the first, second, third, and fourth windings for a first differential inductance in a first mode and to configure two of the first, second, third, and fourth windings for a second differential inductance in a second mode.
