A six-order wideband bandpass sigma-delta modulator
frequency 40MHz with 78dB Dynamic Range in a 0.35µm CMOS process. I. INTRODUCTION Oversampling bandpass A/D is widely used because of its increased accuracy and decreased analog front-end circuitries in transceiver systems. High frequency digital processing is more robust than its analog counterpart, and does not have the analog circuit imperfections. Digital IF extraction is also very benefici...
متن کاملBandpass Sigma-delta Modulator for Wideband If Signals
in Section 6.2, “even” samples are integrated completely independently from “odd” samples. This is modeled in our simulation by the two resonators in Fig. 18. Mismatch between these two resonators does not need to be accounted for because in the actual circuit implementation the two paths share the same amplifier. But both even samples and odd samples are stored alternatively in two different s...
متن کاملBandPass Sigma-Delta Modulator for wideband IF signals
Sigma-Delta modulation techniques have been applied to narrow-band passband signals [Jantzi93]. Recent technology improvement has allowed conversion of GSM channels [Ong97] and DECT channels[Bazarjiani97]. In this report, the main concept behind BandPass Sigma-Delta conversion is briefly explained together with its advantages and applications. The architecture choices for this design are then d...

متن کاملA High Temperature Sigma Delta Modulator Asic
Solid state devices are used more and more to provide computerised control and sensing in high temperature environments. The market for electronics, in instrumentation and control systems in down-hole applications for petroleum exploration, requires increased performance from electronic components in terms of both duration and temperature. Substantial improvements in performance and cost of com...
