An integrated circuit with body-bias inputs coordinated by a switch at initial power application. A switch coupled to the N-well bias and P-type substrate bias lines of an integrated circuit selectively couples the substrate to ground or the substrate bias supply, depending upon the state of the bias...http://www.google.com/patents/US8022747?utm_source=gb-gplus-sharePatent US8022747 - System for substrate potential regulation during power-up in integrated circuits
