“…Production capable single-chip CMOS transceivers will not only require the continued exploration of new transmitter and receiver systems and circuit design techniques [3], [4], [6], [8], [46], but also a better understanding of the devices used by these circuits. In particular, the noise performance of this receiver was found to be significantly worse than that initially predicted.…”

A monolithic 1.9-GHz, 198-mW, 0.6-m CMOS receiver which meets the specifications of the Digital Enhanced Cordless Telecommunications (DECT) standard is described. All of the RF, IF, and baseband receiver components, with the exception of the frequency synthesizers, have been integrated into a single chip solution. A description is given of a wide-band IF with double conversion architecture which eliminates the need for the discrete-component noise and IF filters in addition to facilitating the eventual integration of the frequency synthesizer blocks with on-chip VCO's. The prototype device utilizes a 3.3-V supply and includes a low noise amplifier, an image-rejection mixer, and two quadrature baseband signal paths each of which includes a second-order Sallen and Key anti-alias filter, an eighth-order switched-capacitor filter network followed by a 10-b pipelined analog-to-digital converter (ADC). The experimental device has a measured receiver reference sensitivity of 090 dBm, an input referred IP3 of 07 dBm, a P 01 dB of 024 dBm, and an imagerejection ratio of 055 dBc across the DECT bands.

“…In some recent radio designs [4]- [6] the emitter part consumes significantly less operational power and it occupies much lesser surface of the die than the receiver part. This difference is particularly apparent for the new generation of impulse-based UWB sensors, where transmitters generate only sequences of pulses, and most of the complexity (synchronization, channel estimation, etc.)…”

“…Moreover, in some cases it can achieve essential savings in power consumption, since the emitting part of the sensor radio typically consumes much less power (e.g. 2-5 times) than the receiving one (see [4]- [6]). …”

We consider a hybrid wireless sensor network with regular and transmit-only sensors. The transmit-only sensors do not have the receiver circuit (or have a very low data-rate one), hence are cheaper and less energy consuming, but their transmissions cannot be coordinated. Regular sensors, also called cluster-heads, are responsible for receiving information from the transmit-only sensors and forwarding it to sinks. The main goal of such a hybrid network is to reduce the cost of deployment while achieving some performance goals (minimum coverage, sensing rate, etc).In this paper we are interested in the communication between the transmit-only sensors and the cluster-heads. Since the sensors have no feedback, their transmission schedule is random. The cluster-heads, on the contrary, adapt their reception policy to achieve the performance goals. Using a mathematical model of random access networks developed in [1] we define and evaluate packet admission policies for different performance criteria. We show that the proposed hybrid network architecture, using the optimal policies, can achieve substantial dollar cost and power consumption savings as compared to conventional architectures while providing the same performance guarantees.

“…Clearly, the energy necessary to execute a given algorithm very much depends on the implementation technology. For current radio software projects, emphasis has been placed on low power consumption, see [66] and [55].…”
