In this letter, a memristor-based chirp pulse generator circuit is introduced for ultra-wideband transceivers for the first time. The proposed generator is built using memristor-controlled ring oscillator. Memristor is used to replace the bulky components in the chirp pulse generation such as surface acoustic wave filters and reactive components (capacitor and inductors), which reflects a huge reduction in area and power. The chirp pulse frequency of the proposed circuit varies linearly with time over the pulse duration due to the change in the memristance. The proposed circuit is mathematically analyzed and designed using 65-nm complementary metal-oxide-semiconductor (CMOS) technology. The 500-MHz bandwidth is demonstrated using a 32-ns pulse width complying with the FCC regulations. The power consumption is 84 μW with a 10-MHz pulse repetition frequency (PRF).
