Voltage translation circuit and a voltage-controlled oscillator including the latter |
摘要 |
<p>A voltage translation circuit (116) provides an output analog voltage signal that has a translated voltage of the voltage of an input analog voltage signal over a range of values of the input analog voltage signal. The voltage translation circuit includes an input stage (202) having a circuit node and an input transistor (210) coupled between the circuit node and a power supply terminal, wherein a gate of the input transistor is coupled to receive the input analog voltage signal; a current path circuit (204) in parallel with the input transistor, wherein the current path includes a first transistor coupled between the circuit node and the power supply terminal; and a circuit coupled to provide a variable body bias voltage to a body of the first transistor. A phase-locked loop is provided which comprises a voltage-controlled oscillator including such a voltage translation as its control circuit.</p> |
