Abstract
In this paper, a quadrature oscillator topology is designed using CDTA (Current Differencing Transconductance Amplifier) based allpass building blocks. Low-voltage CMOS realization of the CDTA element is also given, which is used to implement allpass filters. Resulting circuit is capable of working in supply rails between ±0,75V and total power consumption is just 0,75 mW. SPICE simulation results are supplied to verify the theoretical study.
