Abstract

In this paper, an adaptive power amplifier (PA) modulation index controller with temperature compensation is presented for 5.8 GHz dedicated short-range communication (DSRC) transceiver applications. The number of Class-E type PA cores are configurable for amplitude shift keying (ASK) modulation and correction factor due to temperature variation is compensated adaptively in automatic mode to keep constant PA output power. In external mode, the modulation index and correction factor are configurable for the suitable number of core selection for higher PA output power. The design consumes 17.29 nW power and draws 14.41 nA current from 1.2 V supply. The proposed design is fully synthesizable and it needs only 854 gates for its implementation in 130 nm CMOS process with 64 × 153 μm2 of area.
