Abstract
An inductor arrangement has a first inductor structure having one or more inductors at least partially on a first layer and a second inductor structure having one or more inductors at least partially on a second layer. The inductors are arranged such that currents induced by an external magnetic field are substantially cancelled in at least one of the first inductor structure and the second inductor structure. The, or each, inductor of the second inductor structure overlaps, at least partially, the, or each, inductor of the first inductor structure. An oscillator circuit having an inductor arrangement is also presented.
Claims22
An inductor arrangement, comprising:
- a first inductor structure comprising one or more inductors at least partially on a first layer;
- and
- a second inductor structure comprising one or more inductors at least partially on a second layer;
- wherein
- the inductors are arranged such that currents induced by an external magnetic field are substantially cancelled in at least one of the first inductor structure and the second inductor structure;
- and
- the, or each, inductor of the second inductor structure overlaps, at least partially, the, or each, inductor of the first inductor structure.
An oscillator circuit comprising an inductor arrangement, the inductor arrangement comprising:
- a first inductor structure comprising one or more inductors at least partially on a first layer;
- and
- a second inductor structure comprising one or more inductors at least partially on a second layer;
- wherein
- the inductors are arranged such that currents induced by an external magnetic field are substantially cancelled in at least one of the first inductor structure and the second inductor structure;
- and
- the, or each, inductor of the second inductor structure overlaps, at least partially, the, or each, inductor of the first inductor structure.
