A time-to-digital converter (TDC) measures a time interval &#x394;Tbetween a leading signal and a triggering signal. A phase regulator incorporates a looped delay line to create pre-defined sub-intervals Tdetermined by the length of the delay line. The phase regulator has an input receiving the leading signal such that the leading signal loops around the delay line. A counter for counting the number of times m the leading signal loops around the delay line before said triggering signal arrives to obtain a coarse measurement of the time interval defined in terms of the sub-intervals T. A Vernier core for measures a residual time interval Twhere T=&#x394;T&#x2212;mTto obtain a value for the time interval &#x394;T. The TDC uses simpler encoding logic with reduced power consumption and phase noise performance better than 5 dB.

An acoustic filter and method of acoustic filter manufacture provides a plurality of series acoustic resonators coupled in series on a first resonator substrate, a plurality of shunt resonators on a second resonator substrate, and a support substrate. The first and second resonator substrates are mounted on the support substrate. The filter further provides a plurality of electrical connections, wherein each respective electrical connection electrically couples a respective one of the plurality of shunt resonators to a respective one of the plurality of series acoustic resonators.
