ANALOG SWITCH FOR RF FRONT END |
摘要 |
Techniques for improving the linearity of radio-frequency (RF) front-end switches. In an aspect, open-loop techniques are disclosed for superimposing the output voltage of one or more negative rectifiers on a negative substrate bias voltage to reduce the non-linearities associated with voltage-dependent substrate leakage current. In another aspect, closed-loop techniques are further disclosed for maintaining the substrate bias voltage close to a reference voltage. Exemplary embodiments of the circuit blocks are further described. |
