摘要： A group of transistors operate as a combined power amplifier, to amplify signals to be transmitted, and as a low noise amplifier, to amplify signals which are received. In a first mode, the group of transistors is configured to amplify the signals to be transmitted by turning all of the transistors in both a first subset and a second subset on. In a second mode, the group of transistors is configured to amplify the signals which have been received by turning on the first subset of transistors and turning off the second subset of transistors.

摘要： An amplifier for amplifying an input signal in a frequency band, has a quadrature signal divider (116) for dividing the input signal into first (104) and second (110) components. The first component (104) is amplified in a first transistor amplifier (102) having a first frequency response to produce a first amplified component (106). The second component (110) is amplified in second transistor amplifier (108) having a second frequency response, different to the first frequency response, to produce a second amplified component (112). The first (106) and second (112) amplified components are combined in a quadrature signal combiner (120) to produce an amplified input signal. The frequency response of the amplifier is related to the sum of the first frequency response and second frequency response.

摘要： A method for improving or eliminating second harmonic and higher even order distortion terms and balance of fundamental signals in push-pull amplifiers and other differential circuits is disclosed. A common-mode (CM) signal is generated as a sum of two complementary (out of phase) signals in a summation network (32). The CM signal contains even order distortion terms only, while the fundamental signal and odd order distortion terms are canceled, thus providing a correction signal that can be used to reduce even order distortion terms, by injecting the correction signal, with proper phase and amplitude, into suitable circuit nodes. For feedback (70), the correction signal is injected at the input (56, 58) of the amplifiers (16, 18), for feed-forward, it’s injected at the output. The correction signal can be amplified to higher levels and injected into the circuit, without affecting gain of fundamental signals; and can result in significant even order distortion improvements, and improved balance of complementary fundamental signals.

摘要： Double transformer balun for maximum PA (Power Amplifier) power. A novel approach is presented herein by which conversion from a differential signal to single-ended signal may be achieved using a double transformer balun design. The secondary coils of the double transformer balun also operate as a choke for the PA supply voltage. The secondary coils can operate as an RF (Radio Frequency) trap or choke to keep any AC (Alternating Current) signal components and to pass any DC (Direct Current) components. By using a double transformer balun design, relatively thinner tracks may be employed thereby ensuring a high degree of electromagnetic coupling efficiency and high performance. Also, these relatively thinner tracks consume a relatively small amount of space on the die. The double transformer balun design also includes a matching Z (impedance) block that is operable to math the Z of an antenna or line that the PA is driving.

摘要： PURPOSE: A multi-finger type transformer and a power amplifier using the same are provided to reduce area required for a voltage coupling process using an inductor-based transformer. CONSTITUTION: A first loop(110) generates magnetic field by receiving power form a power supplying part. A part of the first loop is open. One end of a pair of input lines(130) is expanded through the opened part of the first loop. Another end of the input lines is in connection with the power supplying part in order to supply power to the first loop. A second loop(120) is shaped into the same shape of the first loop. The second loop is formed at the outside of the first loop in order to generate an inducing current. A part of the second loop is open. One end of a pair of output lines(140) is expanded though the opened part of the second loop. Another end of the output line is in connection with an output terminal.

摘要： A resonance active balun reduces unbalance between differential signals by performing the switching operation of the differential signal generated by a resonant unit. A resonant unit(100) converts the single ended signal through the input terminal into the differential signal. A differential switch part(200) is formed with the cross-linking structure between the differential signal terminal of the resonant unit and the first and second signal output terminals. The differential switch part outputs the differential signal through the first and second output terminals by amplifying the differential signal from the resonant unit and reducing the unbalance at the same time.

摘要： A power amplifier includes a two-dimensional matrix of N×M active cells formed by stacking main terminals of multiple active cells in series. The stacks are coupled in parallel to form the two-dimensional matrix. The power amplifier includes a driver structure to coordinate the driving of the active cells so that the effective output power of the two-dimensional matrix is approximately N×M the output power of each of the active cells.

摘要： The present invention provides a breakdown resistant transistor structure for amplifying communication signals. This structure includes a first NMOS transistor having a source connected to ground and a first gate for receiving the input radio frequency signal. The first gate is disposed above a first insulator and the first NMOS transistor having a first transconductance and a first breakdown voltage associated therewith. Also included is a second NMOS transistor having a source connected to the drain of the first NMOS transistor, a gate connected to the reference DC voltage, and a drain that provides the output for the amplified radio signal, the load being disposed between the reference DC voltage and the drain of the second NMOS transistor. The second gate is disposed above a second insulator, the second NMOS transistor has a second transconductance and a second breakdown voltage associated therewith, and the second insulator may be thicker than the first insulator. This results in the first transconductance being greater than the second transconductance, and the second breakdown voltage being greater than the first breakdown voltage.
