Wideband If Image Rejecting Receiver
US Patent:
6636730, Oct 21, 2003
Filed:
Dec 23, 1998
Appl. No.:
09/220288
Inventors:
Thomas A. Spargo - Hermosa Beach CA
Lloyd F. Linder - Agoura Hills CA
Matthew S. Gorder - Riverside CA
Lloyd F. Linder - Agoura Hills CA
Matthew S. Gorder - Riverside CA
Assignee:
TelASIC Communications, Inc. - El Segundo CA
International Classification:
H04B 112
US Classification:
455302, 455304, 455307, 455313
Abstract:
A system and method for effecting wideband image rejection. In a receiver implementation, the inventive method includes the steps of receiving a first signal in a first frequency band and generating in-phase and quadrature signals therefrom. The phase of the in-phase signal is shifted to provide a second signal and the phase of the quadrature signal is shifted to provide a third signal. A predetermined phase relationship is thereby effected between the second and the third signals. The second and third signals are then summed to provide an output signal which has minimal interference from a mixing signal. In an illustrative receiver application, the phase shifting is achieved via the use of all pass networks. Each of the all pass networks include a differential amplifier having first and second input terminals. The first and the second terminals are connected to a first end of first and second resistive elements, respectively.
Digital Pre-Distortion Technique Using Nonlinear Filters
US Patent:

International Classification:
H04K 1/02
US Classification:
375296, 375297, 375254, 455 631, 330 2, 330149
Abstract:
A linearizer and method. In a most general embodiment, the inventive linearizer includes a characterizer coupled to an input to and an output from said circuit for generating a set of coefficients and a predistortion engine responsive to said coefficients for predistorting a signal input to said circuit such that said circuit generates a linearized output in response thereto. In a specific application, the circuit is a power amplifier into which a series of pulses are sent during an linearizer initialization mode of operation. In a specific implementation, the characterizer analyzes finite impulse responses of the amplifier in response to the initialization pulses and calculates the coefficients for the feedback compensation filter in response thereto. In the preferred embodiment, the impulse responses are averaged with respect to a threshold to provide combined responses. In the illustrative embodiment, the combined responses are Fast Fourier Transformed, reciprocated and then inverse transformed.

Differential Pair Gain Control Stage
US Patent:

Assignee:

International Classification:
G06F 744
H03L 500
H03L 500
US Classification:
327359
Abstract:
A "gain control differential pair" (GCDP) conducts current in response to a differential drive signal, with the gain of a signal path formed via the current circuit of one of its transistors controlled by the drive signal. The GCDP is preferably driven with a drive circuit that receives a symmetrical input signal and produces an offset differential drive signal which has the effect of keeping one of the GCDP's transistors turned off over a wider portion of a symmetrical input signal's voltage range, thereby reducing GCDP-caused noise. One or more GCDPs are implemented as part of a Gilbert mixer to regulate the amount of RF current that flows between the mixer's output and input stages, which eliminates the need to provide gain control in other circuits fed by the mixer. When driven with an offset drive signal, the Gilbert mixer simultaneously provides gain control, low distortion, low power consumption and excellent LO/RF isolation.
