Tuning positioning control method and apparatus
The application relates to a tuning positioning control method and device. A multi-turn absolute value encoder is used to collect the tuning position of a tuning device, the interval of the collected digital position value is far smaller than the precision range of analog-digital conversion, and the hardware or software can be set according to the actual required precision. The tuning precision is high, the error is small, and the tuning matching effect is optimal.

Capacitive element and circuit structure including capacitive element(s)
Disclosed are a capacitive element (CE) and a circuit structure including CE(s). The CE includes series-connected first, second, and third transistors (dual-gate n-type field effect transistors). Shared source / drain regions between the second and first transistors and between the first and third transistors are connected to capacitors, respectively. The first transistor is larger than the second and third transistors. The front gate of the first transistor and back gates of all three transistors receive a first control voltage (VC1). The front gates of the second and third transistors receive a second control voltage (VC2). VC1 and VC2 are concurrently switchable to concurrently switch the three transistors between on and off states. High and low voltage levels of VC1 are at a first positive voltage level and at ground. High and low voltage levels of VC2 are at the first positive voltage level and at a second positive voltage level.

Capacitive element and circuit structure including capacitive element
The invention relates to a capacitive element (CE) and a circuit structure comprising the CE. The CE includes first, second, and third transistors (dual gate n-type field effect transistors) connected in series. Shared source / drain regions between the second and first transistors and between the first and third transistors are respectively connected to a capacitor. The first transistor is larger than the second and third transistors. The front gate of the first transistor and the back gates of all three transistors receive a first control voltage (VC1). Front gates of the second and third transistors receive a second control voltage (VC2). The VC1 and the VC2 can be switched at the same time so as to switch the three transistors between an on state and an off state at the same time. A high voltage level and a low voltage level of VC1 are at a first positive voltage level and ground. The high voltage level and the low voltage level of the VC2 are at a first positive voltage level and a second positive voltage level.
