TIME-INTERLEAVED DELTA-SIGMA MODULATOR FOR WIDEBAND DIGITAL GHz TRANSMITTERS DESIGN AND SDR APPLICATIONS
This paper presents a development of a wideband deltasigma modulator for fully digital GHz transmitters. The fully digital RF transmitter is developed as a promising solution for software defined radio (SDR) terminals and applications. The fully digital transmitter consists of a delta-sigma modulator, a highspeed multiplexer and a switching-mode power amplifier. The speed limitation of delta-si...
متن کاملDigital Compensation Techniques for Transmitters in Wireless Communications Networks Terrestrial and Satellite Systems
Since they appeared, wireless technologies have deeply transformed our society. Today, wireless internet access and other wireless applications demand increasingly more traffic. However, the continuous traffic increase can be unbearable and requires rethinking and redesigning the wireless technologies in many different aspects. Aiming to respond to the increasing needs of wireless traffic, we a...
متن کاملDigital-Intensive Wideband RF Frequency Synthesizers
The evolution of CMOS technology demands new approaches to implement radio-frequency integrated circuits. This paper presents two digital-intensive frequency synthesizers implemented in 65-nm CMOS: a digital period frequency synthesizer and an all-digital phase-locked loop. The experimental circuits cover frequency ranges of 0.1 4.3 GHz and 2.7 6.1 GHz.
متن کاملAnalysing Security-related Signals Using Software-defined Radio
Software-defined radio (SDR) has grown to be a serious alternative to traditional radio architectures. With the higher flexibility of software based filtering and demodulation (compared to hardware modifications necessary in traditional radios), much less expensive receivers and transmitters for specialised broadcast protocols can be built using SDR. With this simplification comes a higher risk...
متن کاملImplementing a Direct RF Transmitter for Wireless Communications - Application Note - Maxim
The application note summarizes the RF transmitter architectures of zero-IF, complex IF, high (real) IF, and direct RF before detailing the benefits of the direct RF transmitter for wireless applications, which have increased with the rise in smartphone and tablet computer use. As the application note shows, the superiority of a direct RF architecture with a high-performance DAC results in redu...
