摘要

For a highly efficient ON-OFF keying (OOK) transmitter, a microwatt-level ultralow-power (ULP) driver and power amplifier (PA) are designed. For efficient amplification with very high optimum impedance in the ULP application, a class-C topology is implemented and loadpull simulations are carried out to show that the proposed PA can achieve good efficiency at high optimum load impedance without any...
