Abstract: A modulated optical radiation field (I) whose modulation amplitude and temporal phase depend on the local position can be detected with a plurality of pixels 1. Each pixel 1 consists of a transducing stage (T) that converts incoming light (I) into a proportional electric signal, a sampling stage (S), two subtraction/summation stages (SUB1, SUM1; SUB2, SUM2), and an output stage. Each pixel can be addressed individually. The optical radiation field (I) is locally sensed and sampled at a frequency that is four times the wavefield's modulation frequency. The subtraction/summation stages (SUB1, SUM1; SUB2, SUM2) accumulate differences of two samples per modulation period, separated by half the period, during several averaging periods; the two stages are time shifted with respect to each other by a quarter period. The resulting two output signals are employed for the determination of the local envelope amplitude and the temporal phase. These pixels 1 can be realized with circuits that consume very little electric power require small areas, enabling the realization of large numbers of pixels in linear or two-dimensional array sensors.

Abstract: In a cellular telephone having a receiving circuit of a direct conversion type using an even harmonic orthogonal mixer, high-pass filters for removing a DC offset component are arranged before and after a variable gain amplifier in a base band circuit. The DC offset component occurred in the even harmonic orthogonal mixer is always constant, and the DC offset component occurred in the variable gain amplifier frequently varies so that a cutoff frequency of the front high-pass filter is set to be lower than a cutoff frequency of the rear high-pass filter, and the frequencies are set to achieve a fast transition response.

Abstract: A dumbbell shaped resonator efficiently couples IF signals from short transmission lines to an output transmission line at a radio frequency (RF) mixer's IF output port. The RF mixer uses short transmission lines and terminating resistors to match impedances within the mixer and to minimize the mixer's distortion. The RF mixer, including the dumbbell resonator, is constructed on a printed circuit board and has a low manufacturing cost. Alternatively, the output transmission line is center-tapped to provide a pair of IF signals having opposite phases.
