摘要： In an analog signal processing device, an output signal and a reference level are compared by a comparator, and a result of comparison is filtered by a low-pass filter. By doing so, an adaptive control signal is generated so as to correspond to a background signal component having a low frequency, included in an input signal, and is negatively fed back to a signal processing unit. With this arrangement, the background signal component is compensated by the adaptive control signal having a frequency band sufficiently separate from a frequency band of a target signal component to be processed, the component being included in the input signal. As a result, a DC level of the output signal is stabilized at the reference level. Therefore, the signal processing device of a capacitive coupling type incorporating an amplifier, an input capacitor, and a feedback capacitor is allowed to carry out an adaptive control operation for keeping a DC level of the output signal to a desired level, with respect to changes in the background signal component or a shift of the input signal from an input reference level (average value), without suspending a signal processing operation. As a result, a spare circuit for a refreshing operation for compensating an off-set voltage of the amplifier can be omitted.

摘要： An encoding apparatus uses a vector quantization encoding method for encoding indexes of codewords, which supply a scalar quantized code of a maximum scalar product value of each code word in a code book, and its maximum scalar product value to a vector component of an input image inputted from an image sensor, so as to output the encoded indexes. A scalar product value calculating circuit in the encoding apparatus has scalar product value calculating sections, which are composed of an analog circuit having a code component capacitor corresponding to each code component, a differential amplifier and a feedback capacitor, corresponding to each codeword, and the scalar product values of the input vectors are calculated in parallel by the scalar product value calculating sections. In such a manner, when the analog calculation is made, the scale of the circuit can be decreased and the power consumption can be lowered. Therefore, unlike the case where the calculation is made after A/D conversion, it is possible to avoid a problem that the number of times of calculations and the power consumption are remarkably increased due to increases in the number of dimensions of the input vector and the number of gradations.

摘要： A winner-take-all circuit for judging a channel receiving an analog signal having the largest or smallest value among multiple channels upon input of analog signals. Each basic circuit includes a detecting unit for comparing an input voltage with a reference voltage, and a feedback current generating unit for outputting a feedback current that determines a judging range in response to an output voltage from the detecting unit. The winner-take-all circuit also includes a tenth transistor serving as a common transistor to all the basic circuits. The tenth transistor secures, even when an input voltage is small, a current that should flow through a sixth transistor serially connected to the seventh transistor that determines an amount of a feedback current from the feedback current generating circuit. As a result, even when there are fewer k channels receiving input voltages having the highest level and slightly lower ones compared with all the n channels, a feedback current is secured in a sufficient amount to vary the reference voltage. In addition, the winner-take-all circuit of the present invention comprises analog circuits, thereby making the structure simpler compared with a counterpart that processes digital signals.

摘要： A correlator which can be adapted to a receiver for impulse radio includes a multiplier for multiplying a received impulse train by a received template train, an analog integrator for integrating the result of the multiplication, and a quantizer quantizing the result of the integration, which result is supplied to a digital integrator. An adder is provided on the input side of the analog integrator, and a negative feedback path negatively feeds the result of the quantization back to the analog integrator via the adder. Quantization errors occurring in the quantizer are negatively fed back to the analog integrator and thereby integrated, then quantized by the quantizer again. As a result, it is possible to reduce quantization errors and to improve the S/N ratio.
