Design and implementation of an active inductor based LC oscillator

In this paper operation of an LC oscillator in two distinct frequency bands, dedicated respectively to Zigbee standard (2.4GHz–2.483GHz) and RFID standard (860MHz–960MHz) is presented. To perform low power consumption and low silicon area, an LC quadrature controlled oscillator using an active inductance has been used. The proposed topology has been simulated under 1.2V supply voltage using the typical model parameters of the 0.13μm CMOS process from STMicroelectronics. At the two separated frequency bands the phase noise is lower than −83dBcHz with frequency offset of 1MHz. At the same simulation condition the total power consumption is 5.5mW only.
