CMOS based RF circuits have demonstrated efficient performance over the decades. However, one bottle neck with this technology is its lossy nature for passive components such as inductors, antennas etc. Due to this drawback, passives are either implemented off chip or the designers work with the inefficient passives. This problem can be alleviated by using inkjet printing as a post process on CMOS chip. In this work, we demonstrate inkjet printing of a patterned polymer (SU8) layer on a 24 GHz oscillator chip to isolate the lossy Si substrate from the passives which are inkjet printed on top of the SU8 layer. As a proof of concept, a monopole antenna is printed on top of the SU8 layer integrating it with the oscillator through the exposed RF pads to realize an oscillator transmitter. The proposed hybrid fabrication technique can be extended to multiple dielectric and conductive printed layers to demonstrate complete RF systems on CMOS chips which are efficient, cost-effective and above all small in size. © 2016 IEEE.Citation
