An 18.8–33.9 GHz, 2.26 mW current-reuse (CR) injection-locked frequency divider (ILFD) for radar sensor applications is presented in this paper. A fourth-order resonator is designed using a transformer with a distributed inductor for wideband operating of the ILFD. The CR core is employed to reduce the power consumption compared to conventional cross-coupled pair ILFDs. The targeted input center frequency is 24 GHz for radar application. The self-oscillated frequency of the proposed CR-ILFD is 14.08 GHz. The input frequency locking range is from 18.8 to 33.8 GHz (57%) at an injection power of 0 dBm without a capacitor bank or varactors. The proposed CR-ILFD consumes 2.26 mW of power from a 1 V supply voltage. The entire die size is 0.75 mm × 0.45 mm. This CR-ILFD is implemented in a 65 nm complementary metal-oxide semiconductor (CMOS) technology.

Programmable Frequency Divider

A low-voltage programmable frequency divider with wide input frequency range is fabricated in standard 0.18µm TSMC RF CMOS technology and presented in this paper. Considering the frequency division ratio of dual-modulus prescaler is relatively smaller, a programmable divider with full custom design is used to increase the frequency division ratio and the maximum operating frequency. The frequency division ratio of the programmable frequency divider covers from 64 to 255. And the measured results show that the programmable divider works correctly when the input frequency varies from 0.5 GHz to 6.0 GHz, with 1V supply. Besides, the power consumption is 3.5 mA at the maximum frequency of 6.0 GHz.
