Don't Try This with CMOS! Video

Abstract: This is really a love story. Not about antique technology, but about a wild period of jaw-dropping creativity, the golden era of the bipolar transistor. The almost magical properties of the BJT and the diverse set of problems it was called on to solve are nothing short of astonishing: an incredibly dense logic family that didn�t need a power supply, a DAC that automatically corrected for transistor sizing, an LDO loop invariant to PVT and load, a multiplier made from one transistor, and an equation for synthesizing�well, almost anything. This is not just nostalgia. It is a lesson in creative thinking. It is a blueprint for the next golden era of circuit magic.
