This work describes an UWB impulse transmitter with integrated antenna in the 60 GHz band implemented in CMOS65nm SOI technology. The transmitter aims low-power short-range high data-rate communication systems for fast-downloading applications. It consists of an oscillator that is switched on-and-off by the digital data to be transmitted and a medium power amplifier. The transmitter is fabricated...
We present the design of an ultra low power sixth-order Butterworth low pass GmC filter in 0.13 ??m CMOS process. A method to optimize the power consumption of a fully differential telescopic OTA is also presented to achieve an input linearity of 220 mVpp and transconductance value of 6 ??S. The OTA is then used to implement an ultra low power filter and to show the impact of parasitic capacitances...
An ultra-low power (ULP) SoC including an IEEE802.15.4 2.4 GHz transceiver designed in 130 nm CMOS technology is presented. Power consumption was minimized by using a concurrent system and design optimization to avoid the over-specification of blocks. A novel minimum complexity partial correlation algorithm is used in the digital baseband receiver and drains an average of 4802 A (packet PSDU=20 bytes)...
This paper presents the concept of using a MEMS piezoelectric actuated tunable inductor in the design of a wideband high performance VCO. Furthermore, a model of the tunable inductor is presented to facilitate the VCO design and simulation. In addition, by means of this model important characteristics of the tunable inductor can be derived enabling a design of the VCO to be superior in phase noise...
