Abstract :
The 77 GHz signal generator for an automotive radar application is presented. The circuit designed and fabricated using 65 nm CMOS technology. A 77 GHz signal is generated by the 38.5 GHz VCO and the frequency multiplier. Also, the signal generator with frequency dividers offers a 2.4GHz signal for external PLL lock. In order to obtain the target frequency against the PVT variation, a wideband VCO is designed with 2 bits capacitor array bank. And 2 stage injection locked dividers are designed with same oscillation core circuits except the inductor. The simulated signal generated output has output power of -5 dBm, current consumption of 100 mA and phase noise of -85 dBc/Hz at 1MHz offset frequency.
