Another mistake that doesn't deserve a top-level comment: the unit abbreviation for "second" is "s", not "S" (that one's the siemens = inverse ohm = former mho, which was a way better unit than the siemens, but that's another discussion...). Thus, "ms" and "ns" rather than "mS" and "nS". This may sound incredibly pedantic, and it is, but it's also one of the tests for attention to detail that I use when interviewing and evaluating an EE candidate, so, y'know, maybe worth learning to get right. Or not, life's short and building stuff out of discretes is more fun. Your call!
