Efficient & Broadband Even-Order Harmonic Multiplication in Standard CMOS

A novel technique to realize highly-efficient passive multipliers in a standard CMOS process is demonstrated to efficiently generate even-order harmonics while simultaneously suppressing odd-order harmonics over broad-bandwidths. This is achieved by improving the cutoff frequency (fT) well beyond a THz. The higher fT combined with proposed nonlinearity...

Improved Auto Exposure for Digital and Smartphone Cameras

This invention is an improved auto exposure (AE) method which, unlike existing AE methods, does not make a middle brightness assumption. As a result, this invention allows for better exposed images, in particular in poor lighting conditions such as front/back lit and low light scenes. The developed method has been implemented on a camera platform and...
