—An inductorless low-noise amplifier (LNA) with active balun is proposed for multi-standard radio applications between 100 MHz and 6 GHz. It exploits a combination of a common-gate (CG) stage and an admittance-scaled common-source (CS) stage with replica biasing to maximize balanced operation, while simultaneously canceling the noise and distortion of the… (More)
large signal theory of active and non-linear wave interactions would also be nice for the students reading this book as a text. This book lacks explanation of the basic concepts for all the circuit theorems. It simply stated the theorems and demonstrated them with examples for the application. There is no discussion on superposition theorem and no index in… (More)
—DARWIN is a tool that is able to synthesize CMOS opamps, on the basis of a genetic algorithm. A randomly generated initial set of opamps evolves to a set in which the topologies as well as the transistor sizes of the opamps are adapted to the required performance specifications. Several design examples illustrate the behavior of DARWIN.
This paper describes a 2.4GHz Wake-up Receiver (WuRx) designed to operate with low-accuracy (<0.5%) frequency references , enabling crystal-less and thus low-cost wireless sensor nodes (WSNs). Robustness to frequency error is achieved by combining non-coherent energy detection with a broadband-IF superheterodyne architecture, and by using a… (More)
— An inductorless LNA with active balun is designed for multi-standard radio applications between 100MHz and 6GHz. It exploits a combination of a common gate stage and a common source stage with replica biasing to maximize balanced operation. The NF is designed to be around 3dB by using the noise canceling technique. Its best performance is achieved between… (More)
—The design of a 100 kHz frequency reference based on the electron mobility in a MOS transistor is presented. The proposed low-voltage low-power circuit requires no off-chip components, making it suitable for application in wireless sensor networks (WSN). After a single-point calibration, the spread of its output frequency is less than 1.1% (3) over the… (More)
