Abstract: Varactors 116 are incorporated in a monolithic microwave integrated circuit (MMIC) 100 to provide voltage-programmable impedance matching at inputs and/or outputs 124. This permits the impedance variations normally caused by manufacturing variations in (e.g.) doping or epitaxial thickness to be easily compensated by adjusting the varactor bias, after all major manufacturing steps are completed. 
     Integrated varactors 116 are also used to provide temperature compensation in an MMIC. A temperature-sensitive voltage is generated off-chip and supplied to each on-chip varactor 116. Each varactor 116 may include a respective voltage-shifting network, so that different varactors implement different capacitance (temperature) functions, to optimally compensate different portions of the MMIC.

Abstract: An SPS CCD memory using two phase clocking in the serial registers and ripple clocking in the parallel registers with interlacing transfer of charge in the parallel registers to the output serial registers. First alternate parallel registers are coupled to the output register through first transfer gates and first storage gates, and second alternate parallel registers are coupled to the output register through second transfer gates and second storage gates. Third storage gates are provided with each third storage gate alternately receiving charge from a first storage gate and a second storage gate with the third gate delivering the charge to the same storage element of the output register. By linearly staggering the endmost gates of the first alternate parallel registers and the second alternate parallel registers, the interlacing of charge occurs at the endmost gate of the parallel registers.

Abstract: A method and apparatus cancels an echo by using an echo replica generated such that a tap coefficient of an adaptive filter is sequentially updated, the echo being received from a transmitting end to a four-wire side through a two'four wire converter and being obtained such that a pulse signal having positive and negative polarities is fed into a receiving end, wherein a difference signal (error signal) between the echo replica and a reception signal is calculated: a correlation value between a signal representing a polarity of the error signal and a signal representing a polarity of the echo replica is calculated: when the correlation value is smaller than a predetermined value, a first of two types of tap coefficients which belong to each of a plurality of taps is updated based on at least the error signal and is set as the tap coefficient of the adaptive filter during a period in which the pulse signal is set in the positive polarity, and a second type of tap coefficient is updated based on at least the error signal and is set as the tap coefficient of the adaptive filter during a period in which the pulse signal is set in the negative polarity; and when the correlation value is larger than the predetermined value, the first and second types of tap coefficients are updated irrespective of the polarity of the transmission pulse on the basis of the error signal.

Abstract: A data display arrangement in which rows of characters are displayed on a CRT, the display information for the characters being provided by stored data which is accessed recurrently for its display in successive scanning fields. Scrolling of the displayed rows of characters is achieved by progressively delaying the start of the addressing of the stored data relative to the start of each scanning field. By using a row mapping memory, the scrolling principle can be extended such that any row of characters can be displayed at any character row position of the display. This, for instance, enables a display not covering the entire screen to be readily centred. Figure 3 shows a block diagram of the scrolling arrangement.
