Abstract | ||
|---|---|---|
This brief presents a dynamic slew enhancement (DSE) technique for improving the transient response in an adaptively biased low drop-out regulator (AB-LDR). This is done by introducing the FAST and SLOW paths in the adaptive bias loop (ABL). The FAST path injects a quick momentary current during low-to-high load transient, whereas the SLOW path keeps the current large during a high-to-low load step. The dynamic current shoots upto quite a high level, as it is combined with the adaptive biasing. When the proposed technique is implemented in a 0.18 mm CMOS technology, the experimental results show the effective reduction of the undershoot (67%), overshoot (66.7%) while maintaining a low quiescent current of 1.1 mA. The settling times during 0-50 mA and 50-0 mA load transients are improved by 74% and 99.9% respectively. |
