A low power high precision trim-less envelope detector for fail-safe circuit in LVDS receiver
This brief presents a trim-less precision envelope detector for fail-safe circuit in LVDS receiver. A preamp is proposed using gm-constant biasing concept to produce an accurate gain of 9.78 dB across PVT covering the full range of the LVDS input common-mode voltage. The preamp produces a fixed outp...
