An Experimental Study on Body-Biasing Layout Style Focusing on Area Efficiency and Speed Controllability
Summary :
Body-biasing is expected to be a common design technique, and then area efficient implementation in layout has been demanded. Body-biasing outside standard cells is one of possible layouts. However in this case body-bias controllability, especially when forward bias is applied, is a concern. To investigate the controllability, we fabricated and measured a ring oscillator in a 90 nm technology. Our measurement result and evaluation of area efficiency reveal that body-biased circuits can be implemented with area overhead of less than 1% yet with sufficient speed controllability.
