Abstract: PURPOSE:To regenerate a PCM signal through the use of a simple circuit by D/A converting the PCM signal, sampling an output by the clock of a prescribed frequency, further, sampling it by the clock multiplied by an integer, and making it pass through an LPF. CONSTITUTION:The D/A converted output is amplified 12, 112, and if the clock of 44.1kHz is '1', 122 is grounded through a switch 22, and a signal is outputted. The switches 32, 132 are controlled by the clock of 44.1X2kHz, and from second sampling circuits 24, 124, the sampled signal of the double frequency of the output of the amplifiers 12, 112 is obtained.

Therefore, for rear stage LPFs 34 and 134, a low grade LPF with a loose attenuation characteristic can be used, then the PCM signal can be regenerated by the circuit constitution of a low cost.

Title: Differential gain step for standard bipolar type ecl processing
Inventor: WEBSTER STEPHEN
IPC: H01L21/8222
Filed: 1994-11-08
Abstract: PURPOSE: To obtain a differential gain stage being employed in a bipolar monolithic integrated circuit having a semiconductor substrate in which the effect of the parasitic capacitance and a capacitor on an amplifier is suppressed. CONSTITUTION: In case of a differential amplifier comprising multilayer monolithic MOS transistors 12, 14, emitters of the transistors are coupled through a capacitor and the differential amplifier practically has an equivalent circuit as shown at 29 because of the stray capacitance therof. When input signals Vin(+) , Vin(-) are delivered to respective nods 56, 60 through unit gain buffer stages 66, 68, the signal voltage Vin across capacitors 46, 52 (i.e., a capacitance CS) can be brought to zero. Consequently, the signal voltage Vin across capacitors 44, 48 (i.e., a capacitance CSUB) becomes the total input voltage to the differential amplifier. Since the signal current required for sustaining these voltages is fed equivalently from buffers 66, 68, effect of the parasitic capacitance CSUB can be eliminated.
