Abstract:
An accumulation-mode MOS varactor is formed with a standard CMOS process and having an anti-symmetric-CV curve. The asymmetric varactor (ASVAR) can efficiently generate even-order harmonics while simultaneously suppressing odd-order harmonics over broad bandwidths. This is achieved without degradation of dynamic cut-off frequency. The improved cut-off frequency of the asymmetric varactor results in efficient even-harmonic generation well into sub-millimeter or terahertz frequencies. This and the inherent adaptive-CV features of the asymmetric varactor result in even-harmonic generation with process variation resilience and can also be utilized for frequency response shaping and for optimizing performance at various driving conditions.

Claim (Index 1):
A frequency multiplier comprising:\n an asymmetric varactor; the asymmetric varactor comprising:\n a first varactor of the asymmetric varactor, and \n a second varactor of the asymmetric varactor; \n the first varactor of the asymmetric varactor comprising:\n a first layer, and \n a third layer; \n the second varactor of the asymmetric varactor comprising:\n a first layer, and, \n a third layer; \n the first layer of the first varactor of the asymmetric varactor electrically connected to the first layer of the second varactor of the asymmetric varactor and to a first bias signal; the third layer of the first varactor of the asymmetric varactor connected to a potential; the third layer of the second varactor of the asymmetric varactor connected to a second bias signal; in response to the first bias signal, the second bias signal, and an input signal, the asymmetric varactor generates an output signal comprising an output frequency that is an even order multiple of an input frequency of the input signal.
