This paper describes an innovative monitoring technology that is used to detect ground-level ozone pollution and is based on the deployment of a network of wireless devices which are connected to a collection of plants and are used as biosensors. Such devices retrieve and transmit the electrical activity signals, which are generated within the plants, and(More)
This paper describes a fully integrated Silicon Germanium (SiGe) Voltage Controlled Oscillator (VCO) chip with 19% tuning range and low phase noise suitable for 10-Gb/s fiber optic transceivers and X-band applications. It consists of two switchable externally enabled VCO’s. The total chip tuning range is 9.2-11.1GHz when the varactor control voltage varies(More)
An integrated 12-GHz static frequency divider with a selectable division ratio (16/1, 64/1) realised in a Silicon Germanium technology dedicated for high volume production, is presented. It operates at low bias voltage (2.7-3.6V) providing balanced output signals on 50-ohm loads. The chosen architecture, the adopted design approach and used technology led(More)
