CNT processor made by MIT and ADI

MIT and ADI have built a 16-bit processor using CNTs. 10 million CNTs were used to form 14,702 CMOS CNT field-effect transistors (CNTFETs), arranged in 3,762 digital logic blocks, that together operated as a 16-bit processor. The chip can fetch 32-bit instructions from memory, has a RISC-V register file, and can read and write 16-bit data ...

Reset chip works on 24V rails and wastes only 300nA

Texas Instruments has introduced a reset chip for voltage rails between 1.5V and 10V, that can work on 24V rails with additional resistors (see below). Called the TPS3840 family, supply current is typically 300nA, and is 700nA max over temperature. Threshold voltage is fixed, and versions are available from 1.6 to 4.9V in 0.1V steps – ...
