As the pixel size of CMOS image sensors (CIS) shrink, problems associated with crosstalk become more severe for devices built using mainstream CMOS processing. This high crosstalk increases the amount ...

An RF power detector based on a CMOS logarithmic/limiting amplifier achieves 50 dB dynamic range at 450 MHz. The logarithmic accuracy is +/- 1dB over the temperature range 0 to 85 degC. The chip is ...
