Torex launches positive voltage LDO regulators based on CMOS
The XD6506 is a series of voltage regulators from Torex Semiconductor that is manufactured using CMOS processes. The positive voltage LDO regulators are qualified to AEC-Q100 Grade 2. The regulators achieve low supply current, 0.8 microA (typical) and consist of a reference voltage...

The quadrature LS7084 Module is a CMOS quadrature clock converter. Quadrature clocks derived from optical or magnetic encoders, when applied to the A and B inputs of the LS7084 are converted to strings of a Clock and an Up/down direction control. These outputs can be interfaced...

landingfield.wordpress.com shows us their progress on how to make a cooled CMOS camera able to be used for astrophotography. In the last post, I uncovered a bug in the Vivado implementation which accidently removes the DIFF_TERM from my input buffer. With that problem solved, I...
