This disclosure is in the field of electronics and more specifically in the field of timing control electronics. In an example, a timing control system can include or use an array of circuit cells, and each cell can provide a signal delay using a fixed delay or interpolation. The interpolation can include, in one or more cells, using three timing signals with substantially different delays to create a delayed output signal. Linearity of the delayed output signal is thereby improved. In an example, an impedance transformation circuit can be applied to improve a bandwidth in one or more of the cells to thereby improve the bandwidth of the timing control system.
