  • Patent number: 8198933
    Abstract: A double balanced mixer circuit comprising a differential pair of first amplifier elements responsive to an RF differential input signal, double differential pairs of second amplifier elements responsive to an LO differential input signal, and differential output terminals connected with the second amplifier paths. Coupling elements provide first and second parallel DC connections between DC voltage supply rails for the first and the double second amplifier paths respectively and a series RF connection of the first and second amplifier paths between the supply rails so as to produce a mixed differential amplified signal at the differential output terminals. The coupling elements include respective transmission lines in the first amplifier paths connected between one of the DC voltage supply rails and respective ones of the first amplifier elements and a common transmission line connected between the other of the DC voltage supply rails and both the first amplifier elements.

  • Patent number: 8130018
    Abstract: A latch module comprising a sense pair of transistor elements coupled together for sensing a differential input signal at input terminals, a level-shift module for producing a differential output signal at output terminals, and a regenerative pair of transistor elements coupled together and with the input pair for holding the output signal through the level-shift module. The latch module also includes a pair of gate transistor elements connected in series respectively with the sense pair of transistor elements and with the regenerative pair of transistor elements and responsive to an alternating differential gate signal to activate alternately the sense pair during sense periods and the regenerative pair during store periods. A current injector provides asymmetric operation by injecting current between at least one of the gate transistors and the corresponding sense or regenerative pair of transistor elements so that the sense periods are of different duration from the store periods.
