摘要： A current mirror circuit is described. The current mirror circuit includes a first transistor and a second transistor. The gates of the first transistor and the second transistor are coupled at a bias voltage. The current mirror circuit also includes an auxiliary transistor that is biased into weak inversion by receiving the bias voltage at a gate of the auxiliary transistor after being reduced by an offset voltage. The sources of the first transistor, second transistor and auxiliary transistor are coupled together. A primary current from the drain of the second transistor is combined with an auxiliary current from the drain of the auxiliary transistor to produce an output current.

摘要： A method for managing a network includes selecting a first database containing a topology of the network, as an active database that is accessible, selecting a second database as a working database for receiving topology updates, discovering a topology of the network and updating the second database with the discovered topology, and selecting the second database as the active database. Another method includes discovering the network, updating a topology representation of the network in a working database based on the discovering, simultaneous with the discovering and the updating providing access to a topology representation of the network in an active database, and exchanging connections of the working and active databases.

摘要： A differential Low Noise Amplifier (LNA) includes a first stage of resistive feedback amplifiers and second stage of complementary amplifiers, where the outputs of the first stage are coupled to the inputs of the second stage in a cross-coupled fashion. An inductive load, such as a transformer, combines signals output from the complementary amplifiers of the second stage. In one example, the LNA has an input impedance of less than 75 ohms, a noise factor of less than 2 dB, and a gain of more than 20 dB. Due to the low input impedance, the LNA is usable to amplify a signal received from a source having a similar low impedance without the use of an impedance matching network between the output of the source and the input of the LNA.

摘要： Disclosed are circuits, techniques and methods for removing one or more harmonics from a waveform that has been mixed with a local oscillator. In one particular example, such a waveform may also be mixed with a second local oscillator at a different frequency and combined with the first mixed waveform to suppress and/or substantially remove the one or more harmonics.
