    摘要: A sample holding circuit applicable as an output circuit for CCD (charge coupled device) or other delay line. The sample holding circuit includes a sample holding stage (11, 12) and at least one amplifier circuit (14,15) connected to the input and/or output of the sample holding stage (11, 12). The amplifier circuit (14, 15) is arranged to amplify a signal at a gain substantially equal to 1 without introducing any DC level shift.

    摘要: A sample-and-hold circuit for sampling a time-­varying signal comprises a main sample-and-hold subcircuit (44) extending between input and output terminals (42, 46) and an auxiliary sample-and-hold subcircuit (48) extending between the input terminal (42) and a portion of the main subcircuit. Each sample-and-hold subcircuit (44, 48) comprises an input buffer amplifier (52, 82), a diode-bridge switch (56, 84) responsive to a control signal and coupled to the input buffer amplifier, a charge-holding capacitor (76, 100) coupled to the switch, and an output buffer amplifier (78, 98) coupled to the capacitor. The output of the auxiliary output amplifier (98) is further coupled to the main switch and the output of the main output amplifier (78) is coupled to the output terminal (46). A generator (62) generates the control signal for controlling the switches (56, 84) such that the same part of the time-varying signal passing through the main and auxiliary subcircuits (44, 48) is sampled. The time-­varying signal passing through the main subcircuit (44) is delayed such that the time-varying signals traveling through the main and auxiliary subcircuits reach the main switch at substantially the same time.

    摘要: A sample-hold circuit comprises a large number of sample-hold elements (2Am, ..., 2Am+5), and a mult-­stage shift register (7A) for controlling sampling timings of the sample-hold elements, including a large number of stages corresponding to respective sample-hold elements, characterized in that each of stages (20, 20m, ..., 20m+5) of the multi-stage shift register includes an input gate (21, 21m, ..., 21m+5) for taking a signal shifted from the preceding stage thereinto, an output gate (22, 22m, ..., 22m+5) for shifting the signal taken in by the input gate to the succeeding stage, respective sampling timings of said sample-hold elements corresponding to respective stages being determined by signals taken in between the input and output gates through the input gates at the respective stages. Waveforms of output signals from respective stages for determining the sampling timing are not affected by interstage wiring capacity. Accordingly, where a multi-­stage shift register is made up as a folded array, unevenness occurs in the interstage wiring capacity, but such an unevenness has no bad influence on the sampling timing.

    摘要: The circuit arrangement includes a low voltage cascode current mirror circuit arrangement having an input branch comprising first and second FETs (T1,T3) and an output branch comprising third and fourth FETs (T2,T4). In order to provide the correct bias potential of V t +2V on at the gate electrodes of the second and fourth FETs (T3,T4) a second output branch comprising two further FETs (T5,T6) and a further current mirror circuit comprising FETs (T7,T8) pass a current through the diode connected FET (T9) so that it produces the voltage V t +V on . If this current is equal to the input current then the diode connected FET (T9) is constructed to have a gate width to length ratio of one quarter of that of the cascode connected transistors (T3,T4). The current mirror circuit is incorporated into current scaling and current memory circuits for signal current manipulation.
