Development of Low-Cost 24-GHz Circuits Exploiting System-in-Package (SiP) Approach and Commercial PCB Technology

Gabriele Tasselli

This paper deals with 24-GHz circuits developed by exploiting a system-in-package approach. In order to reduce the cost as much as possible, a standard multilayer printed circuit board (PCB) technology has been adopted. Such a circuit consists of a package ...

A 2.4 GHz MEMS based sub-sampling receiver front-end with low power channel selection filtering at RF

Christian Enz, Aravind Prasad Heragu Singaiyengar

A sub-sampling RF front end which exploits the intrinsically high quality factor of MEMS devices for performing channel filtering directly at RF is proposed in this work. This narrow band filtering at RF also acts as a good anti-aliasing filter to support ...

A 2.4-GHz MEMS-based PLL-free multi-channel receiver with channel filtering at RF

Christian Enz, Aravind Prasad Heragu Singaiyengar

A low power 2.4-GHz receiver exploiting the intrinsic high quality factor (Q) of Bulk Acoustic Wave (BAW) resonators is presented. A novel way of performing simple integer division of the BAW digitally controlled oscillator (DCO) signal to address multi-ch ...

Slow light fiber systems in microwave photonics

Luc Thévenaz, Sang Hoon Chin

Slow light systems are particularly attractive for analog signal processing, since their inherent limitation to a delay-bandwidth product of 1 is less critical for analog systems such as those used in microwave photonics. We present here the implementation ...

High-energy deep-UV temporal pulse shaping by chirp-assisted broadband frequency conversion

Christoph Peter Hauri

We present a novel and highly efficient temporal pulse shaping technique for the generation of flattop-like picosecond pulses in the deep UV. Using standard sum frequency generation (SFG) of a Ti:sapphire laser but with a pair of properly chirped beams pri ...

Looking Inside Modern Receivers

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain

The principle of wireless communications originates from the need to communicate between two points separated by a distance sufficiently large to prevent the use of wires. This article talks about modern receivers in which the basic building blocks of mode ...

A 0.24-nJ/bit Super-Regenerative Pulsed UWB Receiver in 0.18-mu m CMOS

Catherine Dehollain, Michel Declercq

This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies-3.494 and 3.993 GHz-with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative ...
