摘要： Techniques and structures for tuning integrated, distributed voltage-controlled oscillators (DVCO's) across a wide microwave frequency range are disclosed. One type of DVCO implements a tuning circuit that includes a pair of interconnected amplifying transistors and a current source connected to the transistors, such that a differential voltage input to the circuit adjusts the current to each transistor and effectively adjusts the “electrical length” of one of the transmission lines on which the output frequency is oscillating. This, in turn, adjusts the time delay and thus frequency of the signal propagating on the lines across a wide frequency band. This technique is called “current-steering.” In a preferred embodiment, the tuning circuit is balanced with a complementary tuning circuit to effectively adjust the electrical length of the second transmission line in the oscillator. In another technique that provides for more coarse, but wider range, broadband frequency tuning, the time delay, and thus, frequency, of the DVCO is adjustable by varying the capacitive loading on the transmission lines, by introducing a coupling capacitor between the transmission lines and tuning the intrinsic capacitances of the gain transistors with a dc bias input.

摘要： A phase synthesis network having self healing capability. The phase synthesis network includes two phase rotators that receive I and Q input LO signals, that receive a digital control signal, and that can adjust a phase and a gain in response to the digital control signal. An output of each of the phase rotators provides a respective output signal to a switch. The switch provides a selected one of the respective output signals for mixing with a predetermined one of the respective output signals. Two mixers mix signals from the phase rotators with an RF signal. Two analog-to-digital converters provide a respective digital signal representative of the output of the mixers. A baseband digital processor generates digital control signals that are provided to the phase rotators. The circuit has an output terminal configured to provide an output signal representative of the RF signal.

摘要： Methods of bonding a structure fabricated in polydimethylsiloxane (PDMS) and an integrated circuit chip. The procedures for bonding include providing a substrate, affixing the integrated circuit to the substrate, as needed preparing the surface of the integrated circuit chip to permit bonding, aligning the PDMS structure and the features of the integrated circuit chip, and applying a bonding agent. The bonding agent is cured by exposure to a thermal regime for a suitable length of time. Depending on relative sizes, in some cases, a plural number of PDMS structures can be attached to one chip, or a single PDMS structure can be bonded to multiple chips. In some cases, the integrated circuit chip operates wirelessly. In other situations, the substrate provides electrical communication from the integrated circuit chip to electronic components.
