Title:
STAGGERED-BIAS VARACTOR
Document Type and Number:
WIPO Patent Application WO/2020/113922
Kind Code:
A1
Abstract:
Techniques are described for staggered-bias varactors. For example, a staggered-bias varactor can include a control voltage node, a number of bias voltage nodes, and a number of sub-varactors coupled in parallel. The control voltage node can be configured to receive a single, variable control voltage; and the bias voltage nodes can each be configured to receive a different, fixed bias voltage. Each sub-varactor is configured, so that its equivalent capacitance is a function of a difference between the control voltage and a respective one of the bias voltages; and the equivalent capacitance of the staggered-bias varactor is a function of the capacitances of the component sub-varactors. The number of varactors and the bias voltages can be configured, so that respective non-linear capacitive responses of the component sub-varactors effectively combine to yield a substantially linear capacitive response for the staggered-bias varactor as a whole.
