摘要： A single sampling switch i provided for a plurality of sample/hold function-equipped comparators. Thus, when the sampling switch is turned on, an analog signal is fed to each sample and hold circuit, and when it is turned off, the analog signal fed in at that time is sampled and held in each sample/hold function-equipped comparator. The analog signal values sampled and held in the sample/hold function-equipped comparators are averaged when the averaging switch is turned on. In this manner, since the timing for sampling and holding is controlled by the single sampling switch, a smaller number of switching elements are sufficient and the possibility of the timing for sampling and holding differing between the sample/hold function-equipped comparators is eliminated.

摘要： A serial-parallel type AD converter comprises a first parallel type AD converting portion determining a higher order bit of a digital signal, a second parallel type AD converting portion determining a lower order bit of the digital signal and error correcting circuit. In the first parallel type Ad converting portion, a shifter is connected between a first determining circuit and a first encoder. In the second parallel type AD converting portion, a selector is connected between three second voltage comparator groups and a second determining circuit. The error correcting circuit applies control signals to the shifter and the selector for correcting errors derived from sampling skew of analog input voltages. The shifter determines the connection between the first determining circuit and first encoder in response to the control signal. The selector connects one of the three voltage comparator groups to the second determining circuit in response to the control signal.

摘要： A current source block and a negative resistance generation block are connected in parallel. The negative resistance generation block generates a negative resistance in response to the minute variations of an output voltage. Thus the output resistance of a current source circuit is given by the combined resistance of the negative resistance and the resistance of a resistor in the current source block connected in parallel. The resistance of the resistor in the current source block and the negative resistance are controlled to be substantially the same to thereby increase the output resistance of the current source circuit. The current source circuit serves to increase an output resistance when viewed from an differential output terminal. As a result, use of this current source circuit realizes a differential amplifier providing a high gain.
