Actually this is the from the datasheet of MS3110, a sensor used to measure tiny capacitance change.It might represent an electronically controlled switch, perhaps. Can you give the full URL of the article the circuit come from?
Yeah, it seems you are right. Then does this part in the circuit provides a square wave between 2.25V and 0V? And this part provides a out of phase square wave also between 2.25V and 0V?Have a look at the diagram on page 5. It looks like that symbol represents an electronically controlled changeover switch that connects its left side to one or other of the two rails named on the right.

Thanks a lot!I guess so. I haven't read the data sheet enough to know what signal is controlling all of the switches, but I assume that the triangle shows the position of the switch in a specific case - either the low phase of the control signal, or the high phase. So during one phase of the control signal, all the switches would be connected to the side marked with a triangle, and during the other phase of the control signal, all the switches would be connected to the side opposite the triangle.
Hi, I am working on the transfer function of MS3110, I want to know how the transfer function is derived. I have post another thread on this https://www.electronicspoint.com/threads/ms3110-high-resolution-capacitive-readout-circuit.270929/ , would you please give me some instruction if you have any idea?
