MULTIPLE SOURCE-SINGLE DRAIN FIELD EFFECT SEMICONDUCTOR DEVICE AND CIRCUIT |
摘要 |
Disclosed are embodiments of a variable-delay field effect transistor (FET) having multiple source regions that can be individually and selectively biased to provide an electrical connection to a single drain region. Delay is a function of which of the multiple source regions is/are selectively biased as well as a function of gate resistance and capacitance. Such a variable-delay FET can be incorporated into a phase adjusting circuit, which uses gate propagation delays to selectively phase adjust an input signal. The phase adjusting circuit can be tuned by incorporating non-salicided resistances and additional capacitance at various positions on the gate structure. The phase adjusting circuit can further be modified into a phase adjusting mixer circuit that enables a phase adjusted signal to be combined with an additional signal.
