CMOS LC-oscillator with simulated inductor for QPSK

this paper proposes a novel implementation of a Quadrature LC oscillator using an active inductor on-chip. The significance of active inductor in Quadrature oscillators isdiscussed in many papers. In this lecture we propose a circuit for active inductor in QPSK Oscillator
