    Abstract: Certain aspects of the present disclosure provide an inductor-enclosed switchable voltage-controlled oscillator (VCO), for use in a frequency synthesizer of a radio frequency integrated circuit (RFIC), for example. One example apparatus is a frequency synthesizer that generally includes a first VCO circuit comprising a first inductor and a second VCO circuit comprising a second inductor, wherein at least a portion of the first VCO circuit is disposed inside a loop of the second inductor. According to certain aspects, at least a portion of the second VCO circuit is disposed inside a loop of the first inductor.

    Abstract: An integrated circuit includes a capacitor (e.g., a folded metal-oxide-metal (MOM) capacitor) formed in the lower BEOL interconnect levels, without degrading an inductor's Q-factor. The integrated circuit includes the capacitor in one or more back-end-of-line (BEOL) interconnect levels. The capacitor includes multiple folded capacitor fingers having multiple sides and a pair of manifolds on a same side of the folded capacitor fingers. Each of the pair of manifolds is coupled to one or more of the folded capacitor fingers. The integrated circuit also includes an inductive trace having one or more turns in one or more different BEOL interconnect levels. The inductive trace overlaps one or more portions of the capacitor.

    Abstract: Amplifiers with configurable mutually-coupled source degeneration inductors are disclosed. In an exemplary design, an apparatus (e.g., a wireless device or an integrated circuit) includes a gain transistor and a plurality of inductors, which may implement an amplifier. The gain transistor receives an input signal and provides an amplified signal. The plurality of inductors are mutually coupled, are coupled to the gain transistor, and provide a programmable source degeneration inductance for the gain transistor. The inductors may have a positive coupling coefficient and may provide a larger source degeneration inductance. Alternatively, the inductors may have a negative coupling coefficient and may provide a smaller source degeneration inductance.

    Abstract: A coplanar waveguide may include a first transmission line extending between a first ground plane and a second ground plane at a first interconnect level. The coplanar waveguide may further include a shielding layer at a second interconnect level. The shielding layer may include a first set of conductive fingers coupled to the first ground plane. The first set of conductive fingers may be interdigitated with a second set of conductive fingers that are coupled to the second ground plane. Only a dielectric layer may be between the first set of conductive interdigitated fingers and the second set of conductive interdigitated fingers. The first ground plane, the second ground plane, the dielectric layer, and the shielding layer may form a capacitor.
