Abstract

In this paper, a modified time-delay microwave frequency doubler is proposed. A voltage controlled delay line (VCDL) in the proposed frequency doubler compensates the time-delay mismatching between input and delayed signal. With the delay matching and waveform shaping using adjustable Schmitt triggers, the unwanted fundamental component (f₀) and the higher order harmonics such as third and fourth are diminished excellently. In result, only the doubled frequency component (2f₀) appears dominantly at the output port. The frequency doubler is designed at 1.15 GHz of f₀ and fabricated with TSMC 0.18 μm CMOS process. The measured output power of 2f₀ is 2.67 dBm when the input power is 0 dBm. The obtained suppression of f₀, 3f₀, and 4f₀ to 2f ₀ are 43.65, 38.65 and 35.59 dB, respectively.
