Design of High-Performance Voltage Regulators Based on Frequency-Dependent Feedback
             abstract
Abstract- A novel scheme is presented for achieving high
performance low-dropout (LDO) voltage regulators under the
constraint of low supply voltage. This scheme makes use of a
frequency-dependent feedback factor (FDFF). The FDFF has
simple circuit structure and frequency-dependent gain. When it
is used in the proposed LDO, the low voltage operation ability,
wide-band high power–supply rejection (PSR) characteristic and
excellent transient response performance can be obtained.
Simulation results show that this LDO can work properly at
1.2-V supply voltage, and the overshoot is only 1mV, while the
PSR is better than -40dB from dc to 100-MHz. Therefore, the
FDFF based LDO is well suited for low-voltage ripple-sensitive
applications.
