    摘要: An oversampling converter includes first and second integrators for integrating a difference between an input terminal voltage and feedback voltages, first and second quantizers for quantizing outputs from the first and second integrators, respectively, first and second feedback paths for feeding back as the feedback voltages outputs from the first quantizer to the input sides of the first and second integrators, a differentiator arranged at an output side of the second quantizer, an adder for adding an output from the differentiator and the output from the first quantizer, and a circuit for supplying an output from the first integrator to an input terminal of the second integrator. Two or more quantization loops may be used. When the oversampling converter is used as an A/D converter, A/D converters are arranged in the first and second feedback paths. When the oversampling converter is used as a D/A converter, D/A converters are arranged between the adder and the first quantizer and between the adder and the second quantizer.

    摘要: A level shifting circuit for level shifting an input signal so as to correspond with the operating level of a logic circuit of the next stage. The level shifting circuit comprises a first CMOS inverting amplifier circuit (At) without provision of a feedback loop and a second CMOS inverting amplifier circuit (A 2 ) whose output is coupled to the input through a low impedance element (L1), either the input or the output of the second amplifier circuit (A 2 ) being connected to the input of the first amplifier circuit (A 1 . The second amplifier circuit (Aa) functions as an auto-bias circuit with respect to the first amplifier circuit (A 1 ). The level shifting circuitthus formed makes it possible to remarkably reduce power consumption and occupation area when configured as an integrated circuit.
