ABSTRACT:
A shift register is disclosed in which an n-stage shift-register chain (sr) consists of 2n series-connected, like basic cells (zi) which are driven in antiphase by a first and a second shift clock (C1, C2) from a clock generator (g). The nonoverlap range of the two shift clocks is temperature- and frequency-stable, so that the shift register can be used within a wide frequency and temperature range. Frequency adaptation is accomplished simply by changing resistance values.
