Low-k dielectrics will be required to continue miniaturisation of integrated circuits beyond the 90 nm node. The integration of these advanced materials results in significant reduction of signal delay and power dissipation compared to conventional silicon dioxide. As the technology continues to advance, the implementation of low-k dielectrics for the 65 nm node (Luo, et al., 2004) causes also problems,...
A fully integrated WiMedia/MBOA-compliant RF transceiver for UWB data communication in the 3 to 5GHz band is presented. It is designed in a 0.13mum standard CMOS process with 1.5V single supply voltage. The NF is between 3.6 and 4.1dB over all 3 bands. On the TX side, the P1dB is 5dBm supporting an EVM of -28dB and up to -4dBm output power. A single-PLL LO generation is included
A highly integrated, WiMedia/MBOA compliant RF transceiver for ultra-wideband (UWB) data communication in the 3-5GHz band is presented. The design includes receiver, transmitter and fast-hopping synthesizer. It is designed in a 0.13mum standard CMOS technology for a single supply voltage of 1.5V. The receiver features a measured noise figure (NF) of 3.6 to 4.1dB over the three sub-bands. The transmitter...
The presented wheel speed sensor IC is based on hall effect. Speed and motion direction of magnetic encoder wheels or ferromagnetic target wheels as well as two specific amplitudes of the magnetic input signal are detected. A two-wire current output directly linked to the input signal frequency indicates speed. Direction information and detection of specific amplitudes of the magnetic input signal...
This paper deals with the combination of a powerful 16b microcontroller and a high precision signal acquisition unit. Traditionally, a digital technology, a fast, complex processing unit and precise analog signal handling have been regarded to be incompatible. For the first time a true 10 channel 10 bit A/D converter capable of handling analog signals up to several 100 kHz and with a total unadjusted...
