Printed low-voltage complementary inverters based on electrolyte gated transistors are demonstrated. The printed complementary inverters showed gain of 18 and power dissipation below 10 nW. 5-stage ring oscillators operate at 2 V with an oscillation frequency of 2.2 kHz, corresponding to stage delays of less than 50 μs. The printed circuits exhibit good stability under continuous dynamic operation.
