Description:
This work presents a single chip integrated pulse generator-modulator to be utilized in a short range wireless radio sensors remote control applications. The circuit, which can generate single pulses, modulated in BPSK, OOK, PAM, and also PPM, has been developed in a standard CMOS technology (AMS 0.35 μm). Typical pulse duration is about 1 ns while pulse repetition frequency is until 200 MHz (5 ns "chip" time). The operating supply voltage is ± 2.5 V, while the whole power consumption is about 15 mW. Post-layout parametric and corner analyses have confirmed the theoretical expectations.
