Abstract

This paper presents a wideband Current- Reused Voltage Controlled Oscillator (VCO) with 2- Step Automatic Amplitude Calibration (AAC). Tuning range of the proposed VCO is from 1.95 GHz to 3.15 GHz. The mismatch of differential voltage is within 0.6 %. At 2.423 GHz, the phase noise is -116.3 dBc/Hz at the 1 MHz offset frequency with the current consumption of 2.6 mA. The VCO is implemented 0.13 μm CMOS technology. The layout size is 720 × 580 μm².
