The Design and Optimization of a Novel Hybrid Excitation Generator for Vehicles

open access: yesWorld Electric Vehicle Journal
Silicon rectifier generators, which are single-excitation generators, are commonly used in vehicles. However, a traditional single-excitation generator cannot satisfy the requirements of modern vehicles due to its low efficiency, high failure rate and ...

Equalization of Third-Order Intermodulation Products in Wideband Direct Conversion Receivers [PDF]

open access: yes, 2008
This paper reports a SAW-less direct-conversion receiver which utilizes a mixed-signal feedforward path to regenerate and adaptively cancel IM3 products, thus accomplishing system-level linearization.

Memristive Sisyphus circuit for clock signal generation

open access: yes, 2016
Frequency generators are widely used in electronics. Here, we report the design and experimental realization of a memristive frequency generator employing a unique combination of only digital logic gates, a single-supply voltage and a realistic threshold-

Encoding One Logical Qubit Into Six Physical Qubits [PDF]

open access: yes, 2008
We discuss two methods to encode one qubit into six physical qubits. Each of our two examples corrects an arbitrary single-qubit error. Our first example is a degenerate six-qubit quantum error-correcting code.

Design of Cryogenic SiGe Low-Noise Amplifiers [PDF]

open access: yes, 2007
This paper describes a method for designing cryogenic silicon-germanium (SiGe) transistor low-noise amplifiers and reports record microwave noise temperature, i.e., 2 K, measured at the module connector interface with a 50-Ω generator.
