Title: Generating complementary clock drive signals with differing rise and fall times for a mixer circuit
Inventor: BELLAOUAR ABDELLATIF
IPC: H03D7/14
Filed: 2012-04-19
Abstract: A local oscillator circuit for a mixer comprises first and second generation circuits 600, each of which receives a periodic input signal Vin (fig.6) and produces a modified periodic output signal Vout (fig.6) with a transition time on each rising edge different from a transition time on each falling edge (fig.7). The generation circuits 600 supply the modified local oscillator signals to a mixer comprising transistors 402, 404, 406 and 408. Each rising edge of the signal from one of the circuits 600 crosses each falling edge of a signal from the other of the circuits 600 at a crossing point below the turn-on voltage of the mixer, fig.8. Thus, only one of the transistors 402, 404 or 406, 408 is switched on at any time, which avoids degradation of linearity of the mixer caused by shorting of the baseband input signals VBBQP and VBBQM. Each generation circuit 600 comprises two inverters (transistors 602, 604 and 606, 608, fig.6). The transistor dimensions (channel width or length) are chosen in order to control the rise and fall times of the output signal Vout. Also disclosed is a classâ  AB mixer drive circuit (fig.10) that achieves high linearity and good signal to noise performance.

Title: Suppressing far end audio echo
Inventor: BARRON DAVID
IPC: G10L21/02
Filed: 2012-06-22
Abstract: Residual frequency components of a reference signal are suppressed from an error signal. A magnitude of the frequency domain representation of the reference signal is divided by a magnitude of the frequency domain representation of least mean squared (LMS) filtered representation of the error signal to obtain a frequency domain ratio of the frequency domain representation of the reference signal to the frequency domain representation of the LMS filtered signal. The frequency domain ratio of the frequency domain representation of the reference signal to the frequency domain representation of the LMS filtered signal is multiplied by the frequency domain ratio of the frequency domain representation of the reference signal to the frequency domain representation of the LMSÂ­ filtered signal, to obtain a frequency domain signal having reduced residual frequency components of the reference signal.
