An integrated circuit device has an LC tank circuit for frequency determination, and a switched capacitor circuit for tuning the resonant frequency of the LC tank. The switched capacitor circuit has plural sets of parallel branches, each set comprising a first branch and a second branch, the first and second branches each connecting between a first node and a second node, each branch containing a respective capacitor in series with a switch, the switched capacitor circuit being configured such that, in use, the switch of the first branch is on when the switch of the second branch is off and vice versa.

A computer implemented method of calibrating a device comprising the steps of: deriving an analytic expression for a variable to be optimised of the device in terms of at least one parameter of the device, transforming the analytic expression into polynomial form of the at least one parameter of the device, the polynomial form comprising N coefficients, capturing at least N samples of a value of the variable from the device under calibration, each sample being a result of a different independent pre-determined value of the at least one parameter, applying the captured variable values and the corresponding at least one parameter values to the polynomial form, obtaining optimal values of the at least one parameter from the applying step to calibrate the device.

5G will have to cope with a high degree of heterogeneity in terms of: (a) services (mobile broadband, massive machine and mission critical communications, broad-/multicast services and vehicular communications); (b) device classes (low-end sensors to high-end tablets); (c) deployment types (macro and small cells); (d) environments (low-density to ultra-dense urban); (e) mobility levels (static to high-speed transport). Consequently, diverse and often contradicting Key Performance Indicators need to be supported, such as high capacity/user-rates, low latency, high reliability, ubiquitous coverage, high mobility, massive number of devices, low cost/energy consumption. 4G is not designed to meet such a high degree of heterogeneity efficiently. Moreover, having multiple radio access technologies for multi-service support below 6GHz will be too costly. FANTASTIC-5G will develop a new multi-service Air Interface (AI) for below 6 GHz through a modular design. To allow the system to adapt to the anticipated heterogeneity, the pursued properties are: flexibility, scalability, versatility, efficiency, future-proofness. To this end, we will develop the technical AI components (e.g. flexible waveform and frame design, scalable multiple access procedures, adaptive retransmission schemes, enhanced multi-antenna schemes with/without cooperation, advanced multi-user detection, interference coordination, support for ultra-dense cell layouts, multi-cell radio resource management, device-to-device) and integrate them into an overall AI framework where adaptation to the above described sources of heterogeneity will be accomplished. Our work will also comprise intense validation and system level simulations. FANTASTIC-5G includes partners being active in forerunning projects like METIS, 5GNOW and EMPATHIC ensuring the exploitation of the respective outcomes. The consortium possesses the main stakeholders for innovation and impacting standardization, maintaining Europe at the forefront.
