No one argues, that digital logic is indeed analoh, however you rarely see reliance on a passive element (in analog sense), to be "active" in a digital sense. DRAM is the only widely known example.
- hasmanean 3y agoWell using analog effects in digital logic has its risks…at relativistic speeds the capacitor dimensions will change, altering capacitance. Depending on the direction of travel, it could go up or down. ;)
- dreamcompiler 3y agoIt's only because capacitors let you use fewer transistors. Any effort to shrink memory cells as much as possible inevitably leads to a capacitor-transistor hybrid solution. In logic circuits class they don't talk about areal constraints, but IC designers have to think about such things.
- duskwuff 3y ago> you rarely see reliance on a passive element (in analog sense), to be "active" in a digital sense This technique is referred to as "dynamic logic". It was common in the early days of MOS ICs -- for instance, it was used extensively in the original 6502 -- and still finds some usage in high-performance ICs.
