Low-noise electronic circuit offered for licence agreement
Summary:
A team of researchers from an Italian University in the field of electronic engineering is looking for industrial partners, operating in the field of telecommunications, radio surveillance, aerospace, mobile telephony, radio mobile and static apparatuses, radar apparatuses, jammers, tuning circuits, for license agreement. Technology offer relates to an active inductor, i.e. an electronic circuit simulating the behavior of an inductance by using only suitable biased active components/capacitors.
Description:
The researchers behind this innovative technology focus their research activity in electronic engineering, in the field of design of analog integrated circuits for radio frequency and microwave applications and high-frequency active filters.
The team of researchers has developed an innovative active inductor, specifically an electronic circuit simulating the behaviour of an inductance, which allows at least partially obviating the existent drawbacks with reference to the prior art described below, while ensuring a very low noise.
The electronic circuit of the invention may find extensive and advantageous use in several fields, such as telecommunications, radio surveillance, aerospace, mobile telephony, radio mobile and static apparatuses, radar apparatuses, jammers, tuning circuits.
Currently, a first type of prior art active inductors consists of impedance simulators using operational amplifiers, transconductance amplifiers, or current conveyors as active components. This type of active inductors has maximum operating frequencies of a few MHz, and it is especially used in low and very low frequency applications.
In order to obviate this limitation in frequency, a second kind of active inductors of a known type has been developed, in which such active inductors are mostly implemented in CMOS (complementary metal-oxide semiconductor) technology. This type of active inductors is characterized by low losses, by virtue of the use of NIC (negative impedance converter) circuits; however, the methods that are used to implement the inductance - variability cause a high distortion already at very low powers. Therefore, such active inductors cannot be used in processing signals having the powers generally used in radio-frequency transmissions, thus they are suitable only to process signals with a power in a very narrow range.
In order to obviate this drawback, a third type of active inductors has been developed, which is composed of active inductors having an inductance with fixed value, which use phase compensation networks in order to reduce series resistance. This type of active inductors, combined with the use of transistors as active elements, is potentially capable to process high signal powers with low distortion. However, in a tunable filter consisting of inductances and capacitances, the variation in the center frequency, while keeping a given Q (quality) factor, requires varying at the same time both the inductances and the capacities composing the filter. This is not possible with the inductors of such third class, since they are devices characterized by a preset inductance.
The innovation is protected by a patent granted in the United States of America.
The university is looking for industrial partners for the license agreement.
The stage of development of the invention is a working prototype.
Advantages and Innovations:
Use of feedbacks with consequent reduction of the noise contribution of the circuit.
Possibility to have a Noise Figure lower than insertion losses, as resonant element in the filters.
Tuning of the active inductor obtained exclusively through variable linear networks.
Possibility to vary both the inductance and the series resistance.
High Q (quality) factor.
The low noise property makes it the ideal candidate for the realization of medium power RF and microwave applications such as filters, oscillators and VCOs (voltage-controlled oscillators).
