Abstract
The invention relates to a current mode device (CMD). The CMD comprises a first, a second and a third pairs of voltage controlled current sources (CCS). The first pair has an active load that is controlled by the third pair. The first pair provides a first and a second output signal that drive the second pair. The second pair generates a first digital output signal and a second output digital signal depending on a first input signal and on a second input signal, respectively. The CMD further comprises a first, a second and a third current sources that supply a first current (C1) in the first pair, a second current (C2) in the second pair and a third current (C3) in the third pair. The overall delay depends on a ratio between C1 and C2 and the sharpness of the edges of the signals depend on a ratio between C1 and C3, respectively. Furthermore, the second pair controls the amplification of the first pair by controlling the impedance of the active load.
