No constant current sources exist in this circuit

Jake, don't be to quick! The upper two MOSFETs are not in saturation and can be seen as current sources. Even if the complete demostration is not clear because the cap and the resistor are to small. increase to 100kOhm and 10uF and measure the current of cap and you will see how nice and constant the current is given by the two top side MOSFETS.

Yeah...actually i also forgot to place a large value inductor right after the positive terminal of dc source...which kinda makes the input current provided to the circuit 'almost' constant...my bad

Input to a current source inverter is normally made constant by placing an inductance in series with the dc supply...or thats wat i read
