A Use of Double Integration in Sigma Delta Modulation

Abstract: Sigma delta modulation is viewed as a technique that employs integration and feedback to move quantization noise out of baseband. This technique may be iterated by placing feedback loop around feedback loop, but when three or more loops are used the circuit can latch into undesirable overloading modes. In the desired mode, a simple linear theory gives a good description of the modulation even when the quantization has only two levels. A modulator that employs double integration and two-level quantization is easy to implement and is tolerant of parameter variation. At sampling rates of 1 MHz it provides resolution equivalent to 16 bit PCM for voiceband signals. Digital filters that are suitable for converting the modulation to PCM are also described.

Delta-sigma modulation in fractional-N frequency synthesis

Abstract: A description is given of a delta-sigma ( Delta - Sigma ) modulation and fractional-N frequency division technique for performing indirect digital frequency synthesis using a phase-locked loop (PLL). The use of Delta - Sigma modulation concepts results in beneficial shaping of the phase noise (jitter) introduced by fractional-N division. The technique has the potential to provide low phase noise, fast settling time, and reduced impact of spurious frequencies when compared with existing fractional-N PLL techniques. >

Wideband low-distortion delta-sigma ADC topology

Abstract: A /spl Delta//spl Sigma/ topology with reduced sensitivity to opamp nonlinearities is described. The technique is effective even for very low oversampling ratios, and can be used for any modulation order. Techniques for reducing other nonideal effects are also proposed.

A new bandwidth efficient transmit antenna modulation diversity scheme for linear digital modulation

Abstract: A system is proposed and analyzed, which uses several transmit antennas to achieve diversity in a flat fading mobile radio environment. The signals at different antennas carry the same digital information, but have different modulation parameters (modulation diversity). In contrast to other proposals, no bandwidth expansion is required. Modulation diversity for quadrature amplitude modulation (QAM) type modulation is achieved by using different partial response type base pulses. Simulation results confirm the expected gain. >
