A 1-Mega Pixels HDR and UV Sensitive Image Sensor With Interleaved 14-bit 64Ms/s SAR ADC

This thesis presents a 1-Mega pixels high-dynamic range and UV sensitive image sensor in 0.18 µm technology with 14-bit interleaved 64Ms/s SAR ADC. It can achieve 64 fps and 101 dB dynamic range. The pixel array contains three kinds of pixel: UV pixel, visible pixel and low blue pixel. Those three kinds of pixel form a special 4×4 kernel to meet...

Compressive Power Spectrum Estimation: Further study on Non Uniform sampling and Parametric Approach

In the recent development of wireless communication several applications, such as spectrum sensing for cognitive radio are only interested in the power spectrum. These applications do not require the reconstruction of the original analog signal. According to the Whittaker-Kotelnikov-Shannon-Nyquist theorem, the sampling rate must be at least...

Design Study on the Switched and Linear Operation of Broadband CMOS Class-E Power Amplifiers

This research work aims to gain understanding of the power amplifier (PA) operating as a linear PA under low power drive conditions and as a switch-mode PA in high power drive conditions both with the same Class-E load. Two approaches were taken here. Firstly, an analytical approach was developed to investigate the switching operation of...
