    摘要: A signal generator consistent with certain embodiments of the invention has a reference clock (34) producing a periodic sequence of reference clock output pulses. A window generator (38) generates a plurality of time windows through which a selected plurality of the reference clock output pulses are selectively passed as windowed pulses so that the windowed pulses form a selected pattern of pulses. A programmable delay (46) has resolution of delay that has finer time granularity in delay than the period of the clock output pulses. The programmable delay (46) delays each of the windowed pulses by a programmed delay time to thereby provide a timing correction to the windowed pulses to produce an output pattern of pulses.

    摘要: A frequency extension circuit, consistent with certain embodiments of the present invention has a first delay line (108) having a plurality of taps. The delay line receives a reference clock at an input with a clock rate of FREF. A second delay line (104, 150) also receives the reference clock at an input. A logic circuit (130, 134, . . . , 138, 140) combines signals from the delay line taps of the first delay line (108) with signals from the delay line taps of the second and/or first delay line (104, 150, 108) to produce a collection of clock pulses having a combined clock rate of FREF*2N. At least one of the delay lines can be locked to the reference clock using a delay locked loop. The clock pulses can be logically combined with a seed register (204) contents to produce a recursive sequence or with data for convolutional encoding, or with pilot data for correlation in a CDMA transceiver.

    摘要: A delay locked loop circuit 300 consistent with certain embodiments of the present invention has a delay line 304 with coarse adjustment 322 and fine adjustment 360 inputs. The coarse adjustment input 322 provides an overall adjustment of all of the delay line's delay elements while the fine adjustment inputs 360 permit adjusting the individual delay value of each delay element. A first multiplexer 330 receives the delay tap outputs and produces a first selected output while a second multiplexer 334 also receives the delay tap outputs and produces a second selected output. A measurement circuit 344 measures a difference between the first and second output as a measurement of a selected delay element's delay value. An error calculator 346 receives the output of the measurement circuit and calculates fine adjustment voltages for each of the selected delay elements. A tuning circuit 350 applies the fine adjustment voltages to the fine adjustment inputs of the delay line 304.

    摘要: A compensated signal source (210, 220) utilizes baseband signals and a radio frequency carrier signal to generate a set of source output signals (226, 227) which are coupled to a particular circuit (230, 240, 250). The signal source (210, 220) is operable in a characterizing mode in which a test configuration is applied, and outputs from the signal source and the particular circuit measured to develop parameters representing imperfections within the signal source and within the particular circuit. The signal source (210, 220) is operable in a normal mode, in which compensation based on the measured parameters is applied to account for the imperfections. In a preferred embodiment, the particular circuit (230, 240, 250) and compensated signal source (210, 220) form part of an amplifier (200) that implements linear amplification using nonlinear components (LINC) techniques.
