Abstract
A ring oscillator includes (2N+1) inverting delay circuit cells, and each delay circuit cell has an input port and an output port, where N is an integer larger than zero. Each of these (2N+1) inverting delay circuit cells receives a control voltage, and all of the (2N+1) inverting delay circuit cells are electrically connected with each other in series. Furthermore, the input port of one of the (2N+1) inverting delay circuit cells is electrically connected with the output port of an adjacent delay circuit cell of the (2N+1) inverting delay circuit cells.
