Abstract: An apparatus having means for amplifying a differential voltage signal. The means for amplifying includes at least an input stage and an output stage. The output stage includes means for preventing a trade off between a reduction in noise of an output voltage signal and an increase in a dynamic range of the output voltage signal.

Abstract: A bandpass sigma-delta modulator using acoustic resonators or micro-mechanical resonators. In order to improve resolution at high frequencies, acoustic resonators or micro-mechanical resonators are utilized in a sigma-delta modulator instead of electronic resonators. The quantized output is fed back using a pair of D/A converters to an input summation device. In fourth order devices, the feed back is to two summation devices in series. Such a sigma-delta modulator is usable in a software defined radio cellular telephone system and in other applications where high-frequency and high-resolution A/D conversion is required.
