Quadrature oscillator using CDTA-based integrators
... The gate terminals of output transistors M11 and M12 in the current-differencing section are connected to bias-voltages to provide drain output and high impedance at the z terminal (ideal current-controlled current source, CCCS). The multiple-output (MO) CDTA can be easily implemented by copying the ...
