    摘要： A voltage regulator with an adaptive bandwidth, including a first buffer chain, a voltage generating unit, a trimming capacitor unit, a second buffer chain, and a control unit. The first buffer chain delays a clock signal using an external voltage as a supply voltage. The voltage generating unit generates a regulated voltage on the basis a reference voltage. The trimming capacitor unit controls a load capacitance of the voltage generating unit. The second buffer chain delays the clock signal using the regulated voltage as a supply voltage. The control unit adjusts the load capacitance by detecting a delay difference of clocks output from the first and second buffer chains.
