摘要： An improved RF CMOS transistor design is described. Local, narrow interconnect lines, which are located substantially above the active area of the transistor, are each connected to either a source terminal or a drain terminal. The source and the drain terminal are arranged orthogonally to the local interconnect lines and each terminal is significantly wider than a local interconnect line, in an example, the local interconnect lines are formed in a first metal layer and the source and drain terminals are formed in one or more subsequent metal layers.

摘要： An apparatus for propagating local oscillator signals in a circuit, the apparatus comprising two pairs of lines carrying respectively differential in-phase and quadrature signals. The lines are arranged such that in at least one region along their length one of each pair of lines crosses the other of the pair to create a twist. The twist(s) in each respective pair of lines is offset from the twist(s) in the other pair of lines such that the portion of their length over which the in-phase lines magnetically couple to the quadrature lines with a positive coupling coefficient is substantially equal to the portion of their length over which the in-phase lines magnetically couple to the quadrature lines with a negative coupling coefficient.

摘要： A SRAM memory element comprises an influencing element which sets the state of the memory cells within the memory element on start-up to defined values. These defined values are set at the design stage such that on start-up the volatile memory contains firmware or other data. Dependent upon the implementation of the influencing element, the values of stored in the memory cells may be fixed or may subsequently be overwritten during operation of the device. The memory cell may comprise two cross-coupled inverters and the influencing element comprises at least one transistor arranged to connect the input to one of the inverters to ground or a power supply rail when voltage is applied to a controlling node of the transistor.
