摘要： A differential amplifier circuit comprises a series combination of a p-channel type first input transistor and an n-channel type first load transistor coupled between a first constant current source and a discharging line, a series combination of a p-channel type second input transistor and an n-channel type second load transistor coupled between the first constant current source and the discharging line, and a controlling circuit coupled to gate electrodes of the first and second load transistors, and the controlling circuit increases the channel conductance of one of the first and second load transistors when the associated first or second input transistor decreases current passing therethrough in response to a non-inverted or inverted input signal, thereby improving the gain of the differential amplifier circuit.

摘要： A code converter includes a signal converter converting an input digital signal into an intermediate digital signal of two's complement. A subtracter has a minuend input node, receiving lower bits of the intermediate digital signal, and a subtrahend input node. A digital integrator receives an output from the subtracter, a digital comparator receives an output from the digital integrator, a delay unit receives an output from the digital comparator to execute a one-sampling period delay. An output from the delay unit is applied to the subtrahend input node of the subtracter, and an adder receives the remaining upper bits of the intermediate digital signal and the output from the digital comparator, a converted output digital signal being produced from the adder.

摘要： A low-pass filter is inserted between a two-wire line and a four-wire transmitting line for transmitting a transmission signal supplied from the two-wire line. Input and output signals of the low-pass filter are fedback to a subtracter to provide a subtracted signal which is added to an output signal of a terminal impedance resultant filter. Thus, operation is realized in a stable manner even in a high frequency band, in which an output signal of the low-pass filter is rotated in phase by 180.degree..

摘要： A noise shaper includes an incomplete integrator which conducts an addition of a present data and a last sampled data stored and a positive coefficient smaller than 1, a complete integrator which conducts an addition of a storage data before one sample delay and a present data, a three-value quantizing circuit which outputs 0, +1 or -1 signal as an output signal, and a feedback circuit which feeds-back the output signal from the three-value quantizing circuit to the incomplete integrator and the complete integrator. The noise shaper may further include a delay-data supply selection circuit which supplies the last sampled data stored and the positive coefficient to the incomplete integrator only when the output signal supplied from the three-value quantizing circuit through the feed-back circuit is zero. The output signal from the noise shaper can be made zero without deteriorating signal to noise (S/N) ratio when no input signal is inputted to the noise shaper.
