抄録

In this paper a low-power low-dropout (LDO) regulator for p power amplifier (PA) in on–off-keying (OOK) transmitters is proposed. The proposed technique needs no external output capacitors, enabling small-area and low-cost implementation. The response of a rapid load change in an OOK transmitter is improved by the proposed adjustable charge injection (ACI) technique that uses timing information of a transmitted data signal. The designed regulator with the ACI technique has been fabricated in a standard 180 nm CMOS process and achieves 100 mV pp dropout voltage ripple. The measured current dissipation is 65 µA at a power supply of 1.8 V.
