“…After the SCL latches, two inverters reconstruct the logical levels, control the load matching and provide isolation. With a custom optimized design and dedicated layout, this topology has proven applica- bility for low-power design in current deep-submicrometer technologies [4]. However, the topology could be very sensitive to the VCO oscillation amplitude variations when temperature increases.…”

In this work a CMOS 1.2V 5GHz low-power voltagecontrolled oscillator (VCO) is proposed. It uses an on-chip biased LC-tank topology and introduces a temperature compensation technique which stabilizes the oscillation amplitude for a robust I/Q generation using a frequency divider-by-2. Compared to a standard design with constant bias, it reduces the oscillation variation by almost two orders of magnitude between 0ºC and 100ºC with negligible impact on the phase noise. Worst case estimations of the VCO phase noise after layout parasitic extraction are-110.1dBc/Hz and-126.6dBc/Hz at 1MHz and 5MHz offsets from the carrier, respectively. Its nominal current consumption is 198µA (plus 22.5µA for biasing) and it occupies 370x530µm 2. I.

“…The Quality factor is increased with multi-metal layer inductor, which reduces DC resistance and HRS reduces substrate effect at 5GHz tuned oscillator. In paper [ [5]], LC tank is used with complementary cross coupled negative resistance, which is tail biased with NMOS current mirror course. Symmetrical inductor and PMOS varactors in inversion mode are used for fine tuning and metalmetal capacitor array is used for additional coarse tuning for process variation changes, which is controlled by 3-bit signal.…”
