| 20100166114 | METHOD OF REDUCING D.C. OFFSET - A method of reducing d.c. offset comprises comparing the a first variable signal with a second variable signal, producing a control signal in dependence upon the comparison, providing the control signal to a charge pump for generation of a feedback signal, and varying the first signal and/or the second signal in dependence upon the feedback signal thereby reducing any difference between the d.c. level of the first signal and the d.c. level of the second signal. | 07-01-2010 |
| 20090251176 | FREQUENCY DIVIDER CIRCUITS - A circuit for deriving an output clock signal from an input clock signal, the output clock signal having a frequency which is 1/Nth of the frequency of the input clock signal, where N is an odd number. The circuit comprises a plurality of latches configured as a latch ring, the latches being arranged in successive pairs, each pair of latches comprising a first latch that switches on one of the rising or falling edge of the input clock signal, and a second latch that switches on the other of the rising or falling edge of the input clock signal. An RS flip flop is coupled to receive at one of its set and reset inputs an output from the latch ring that is switched on a rising edge, and at the other of the set and reset inputs an output from the latch ring that is switched on a falling edge. Said output clock signal is provided at an output of the RS flip flop. | 10-08-2009 |
