Abstract: A variable attenuator can be used with high-voltage radio-frequency signals. The attenuator can provide wide dynamic range with little loss at the lowest attenuation level. The attenuator may be implemented in digital integrated circuit processes and occupies small integrated circuit area. Additionally, the use of circuit elements external to the SoC may be reduced. The attenuator uses multiple attenuator cells connected in parallel to an RF input and RF output. The attenuator cells use capacitive dividers with pair of capacitors laid out in the same integrated circuit area. The capacitors are also laid out so that the RF input shields the RF output from ground to avoid parasitic capacitance on the RF output.
