A clock generation device includes a first delay unit, a frequency divider, an angle delay unit and a first calculating unit. The first delay unit receives an input clock and delays the input clock by a first preset period to generate an input delay clock. The frequency divider divides a frequency of the delay clock to generate a first frequency-divided clock and a second frequency-divided clock. A frequency of each of the first frequency-divided clock and the second frequency-divided clock is a preset multiple of the input delay clock. The angle delay unit delays the first frequency-divided clock by a second preset period to generate a first delay clock. The first calculating unit determines a trigger time of a first edge of a first output clock with reference to voltage levels of the first frequency-divided clock and the first delay clock and determines a falling time of a second edge of the first output clock with reference to voltage levels of the input clock and the first delay clock.

Time-Mode Signal Processing (TMSP) offers a means for offsetting some of the challenges for analog circuit designs when exploiting CMOS circuit processes designed for digital applications. It would therefore be beneficial to provide a digital method for the storage, addition and subtraction of Time-Mode variables as these offer significant benefit to providing TMSP techniques and expanding their exploitation within devices, systems, and applications. While driven by CMOS process challenges the TM circuits outlined may exploit essentially any digital circuit technology since they are based upon delay. The inventors present an approach to TM variables wherein a switched delay unit is exploited and adopted such that the instantaneous phase difference between two rising signal edges can be latched and used to perform various arithmetic operations. Beneficially, the technique allows analog sampled-data signal processing to be implemented within digital circuitry.

Circuits and a method for tuning an integrated circuit (IC) are disclosed. The IC includes multiple programmable fuses coupled to a control block. The programmable fuses used may be one-time programmable (OTP) fuses. The control block reads settings or data stored in the programmable fuses. A tuning circuit coupled to the control block receives the delay transmitted by the control block. The tuning circuit allows tuning of the IC without changes to the fabrication mask. The tuning circuit may include delay chains to provide additional delay to the IC when needed and the delay in the tuning circuit is configured based on the delay value stored in the programmable fuses and transmitted by the control block.
摘要:
A device for generating and radiating radio frequencies. The device includes a transmission line, a source, and a means for applying a voltage impulse to the transmission line from a low impedance source. A quarter-wave trap is added between the source and the transmission line to suppress the onset of a parasitic radiating mode. The quarter-wave trap also acts as an antenna to transmit the energy to the surrounding environment from the transmission line, which is behaving as an oscillatory circuit. The low impedance source is an electrically driven impulse generator. As a further modification, a second antenna can be attached to the free end of the transmission line to enable lower frequencies to be transmitted.

An electromagnetic generator for working electrically conducting objects with current and magnetic field pulses having a high rate of rise as expressed by dI/dt and dB/dt includes primary windings of a pulse transformer that are arranged in pairs so that their primary currents generate a single current pulse on the secondary side of the pulse transformer. The pulse transformer has as secondary coil comprised of a longitudinally slit pipe on which the insulated primary windings are placed. Contact blocks are attached as current outputs next to the longitudinal slit and in the middle of pipe for the connection of an external low-ohmic peak-current loop which encloses a magnetic field concentrator that is made in one or several parts and that can accept one or several metal work pieces.
