Abstract

Devices (101-105) comprising latches (1-3) with tracking circuits (4) for, in tracking modes, tracking data signals and with deciding circuits (5) for, in deciding modes, deciding about the data signal can use their available time more efficiently by, in the tracking modes, preparing the deciding circuits (5). Thereto, the deciding circuits (5) are not to be switched between disabled/enabled situations, but are to be kept enabled. The tracking circuits (4), in the tracking modes, supply signal values derived from the data signals to the deciding circuits (5), and the deciding circuits (5), in the deciding modes, amplify the signal values. The tracking circuits (4) comprise diodes (21,22) to allow reduced voltage swings in the data signals to be sufficient for proper performances of the latch (1-3). Such reduced voltage swings allow the latches (1-3) to perform at higher speeds. The parasitic capacitors present between the cathodes of the diodes (21,22) form capacitances for storing the signal values and allow the deciding circuits (5) to be prepared.
