This paper investigates a high power factor switch-based wireless power transfer front-end circuit for heterogeneous systems. This circuit uses an integrated switching rectifier, implemented in 0.18um 1.8V/5V CMOS process. An integrated pair of phase synchronizers is used to align the waveshape of a wirelessly-coupled sinusoidal voltage source in the receiving coil to the corresponding conducting...
A photo-electron detection system with 32 PIN photodiodes in 1D array has been designed and implemented within 16cm width. There are mainly two parts in this system: the photodiode frontend with weak signal modulation and sampling, the signal processing backend with parallel signal processing and data transfer. The weak current signal of 32 PIN photodiodes' output is first amplified for about 104...
Orthogonal frequency division multiplexing (OFDM) system performance degrades due to symbol misalignment. We propose a symbol synchronization scheme based on channel estimation (CE). We applied linear interpolation in time domain and Winner filter in frequency domain to implement CE. The first path time delay of channel determines symbol timing offset. We perform inverse fast Fourier transform (IFFT)...
Reconfigurable architecture is considered as very efficient, attack resistant and suitable for cryptograph applications. But the low utilize ratio of on-chip resources and lack of software programmability of traditional reconfigurable arrays draws the advantages back. In this paper, we proposed a reconfigurable SoC with a programmable dataflow structure which consists of multiple configurable pipelines...
We demonstrate a passive synchronization between a high power nanosecond fiber laser and a femtosecond Ti:sapphire laser with a cavity-length mismatch tolerance up to 8 cm and a timing jitter of 13 ps.
Mutual fluctuations between two carriers in a broadband millimeter-wave communication system may be observed from the heterodyne signal spectrum of the carriers. Laboratory measurements made on equipment developed for local multipoint distribution system (LMDS) applications indicated the degradation in the heterodyne spectrum was mainly in the form of increased background noise with L(f) close to...
