Abstract: A frequency doubler (tripler, or quadrupler) employs current re-use coupled oscillator technique to enhance phase noise without increasing current consumption. Frequency doubler uses coupling between two oscillators running at different frequencies; a first oscillator is running at the target frequency and a second oscillator is running at half the frequency. The coupling between the two oscillators is via a transformer having a primary transformer coil and a secondary transformer coil. The first oscillator comprises a differential inductor, coarse/fine tuning capacitor arrays, and an n-type trans-conductor (GM). A virtual ground node of the n-type GM is coupled to one side of the primary transformer coil and the other side of the primary coil is coupled to the center tap of the secondary coil. The second oscillator comprises the secondary coil, coarse/fine tuning capacitor arrays, n-type GM, frequency tracking loop (FTL) and 2nd-harmonic LC filter network.

The gene expression by the infarcted tissue-targeting bacterium of the present invention in infarcted myocardium or infarcted brain is remotely controllable.

Abstract: A re-circulating time-to-digital converter (TDC) can include a triggered reference ring oscillator (TRRO) and a delay module. The triggered reference ring oscillator can, when triggered by a reference signal edge, generate a periodic ring oscillator signal with a ring oscillator period that is a selected ratio of a voltage-controlled oscillator (VCO) period. The delay module can store, in a plurality of latches, samples of a VCO signal docked by the periodic ring oscillator signal. Each latch can generate an output of the sample, and each latch output can represent a time difference polarity between VCO signal and TRRO signal. In another example, the re-circulating TDC can include the triggered reference ring oscillator, a digital frequency lock module, and a TDC post-process module. The digital frequency lock module can generate a ring oscillator control signal, which sets the ring oscillator period for the triggered reference ring oscillator.
