In this paper a novel 0.6 V dynamic biased, body driven Strong Arm latch is presented. The proposed topology exploits a charge pump based dynamic biasing configuration that boosts the effective supply headroom. In addition, the body terminals are used to drive the input pair while the gates are driven by the clock signal to allow for the removal of the tail transistor, resulting in larger peak currents and smaller parasitic capacitances. This reduces power consumption and delay. Moreover, the body driven approach enables rail-to-rail input common mode range (ICMR). As a result, the proposed topology is capable of high-speed operation (up to 2.5 GHz) despite the low supply voltage. At 2.5 GHz the comparator shows a competitive energy-delay product (EDP) of 2.98 fJ/GHz.

Abstract
In this paper a novel 0.6 V dynamic biased, body driven Strong Arm latch is presented. The proposed topology exploits a charge pump based dynamic biasing configuration that boosts the effective supply headroom. In addition, the body terminals are used to drive the input pair while the gates are driven by the clock signal to allow for the removal of the tail transistor, resulting in larger peak currents and smaller parasitic capacitances. This reduces power consumption and delay. Moreover, the body driven approach enables rail-to-rail input common mode range (ICMR). As a result, the proposed topology is capable of high-speed operation (up to 2.5 GHz) despite the low supply voltage. At 2.5 GHz the comparator shows a competitive energy-delay product (EDP) of 2.98 fJ/GHz.File | Dimensione | Formato | |
