Abstract: New results are presented, offering insight into the performance and optimization of linear and adaptive delta modulation, together with a comparison with pulse code modulation. The results ...

Abstract: A highly linear multi-level switched-capacitor (SC) digital-to-analog converter (DAC) is proposed for continuous-time delta-sigma modulators (CTDSMs). A Gm-C CTDSM with a passive frontend ...

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

A delta-sigma converter uses many samples from the modulator to produce a stream of 1-bit codes. The delta-sigma ADC accomplishes this task by using an input-signal quantizer running at a high sample ...

A quadrature modulator from Linear Technology is optimised for direct conversion from baseband to the 850-965MHz frequency band for GSM, EDGE, CDMA2000 basestations and 900MHz RFID readers. The LT5558 ...
