Abstract
Tunable delay circuit devices have an input port, an output port, at least three parallel paths connecting the input port and the output port, on each path, an input switch and an output switch, and on each path, a plurality of shunt resonant tanks connected between the input switch and the output switch, each shunt resonant tank periodically chargeable from the input port and dischargeable to the output port by operation of the input switch and the output switch.

A tunable delay circuit device comprising:
- an input port;
- an output port;
- at least three parallel paths connecting the input port and the output port;
- on each path, an input switch and an output switch;
- and
- on each path, a plurality of shunt resonant tanks connected between the input switch and the output switch, each shunt resonant tank periodically chargeable from the input port and dischargeable to the output port by operation of the input switch and the output switch;
- wherein each of the shunt resonant tanks includes at least one of:
- a thin-film piezoelectric resonator;
- or
- a piezoelectric layer, a first conductive material layer comprising at least a first electrode on a top surface of the piezoelectric layer, and a second conductive material layer comprising at least a second electrode on a bottom surface of the piezoelectric layer.
A method of operating a tunable delay circuit device comprising, providing the tunable delay circuit device including:
- an input port;
- an output port;
- at least three parallel paths connecting the input port and the output port;
- on each path, an input switch and an output switch;
- and
- on each path, a plurality of shunt resonant tanks connected between the input switch and the output switch;
- the method comprising:
- operating the input and output switches to periodically charge each shunt resonant tank from the input port;
- and
- operating the input and output switches to periodically discharge each shunt resonant tank to the output port;
- and introducing three low-loss poles into the device for each of the plurality of shunt resonant tanks.
