“…TDAs have been presented in various types of structures. Charge domain TDA [20][21][22] is a kind of TDA that first changes the time difference to the charge and then amplifies the charge amplitude, and the amplified amplitude is changed into the voltage by the capacitor. Finally, this voltage is converted to the time difference by the comparator.…”

Time-to-digital converter (TDC) is one of the important blocks in most of the digital systems that need to have high resolution. Time difference amplifier (TDA) is used in TDC for increasing the resolution. In this study, an all-digital TDA is proposed. The proposed TDA uses the delay lines with difference delay for amplifying. The proposed circuit is designed and simulated in 65 nm CMOS technology and has a gain of ten and a chip area of about 0.003 mm 2. The calculated maximum gain error is 5%. The proposed TDA consumes 0.94 mW power under 1.1 V supply voltage.

“…Time amplification is needed when processing a small time variable. It is often realised using a dual-slope approach where two pre-charged capacitors of different capacitances are discharged with different currents and a voltage comparator to detect the time instant at which the voltages of the capacitors are equal [11,12]. This approach does not scale well with technology due to the need for two constant current sources.…”

This study provides a comprehensive treatment of the design techniques of all-digital arithmetic units for time-mode signal processing. The arithmetic units investigated include time polarity detectors, time absolute-value generators, time adders, time baluns, time amplifiers, time quantisers, time registers, and time integrators. The principle, circuit implementation, constraints and limitations of these units are investigated in detail. An emphasis is given to time adders and time integrators. An in-depth study of time adders constructed from switched delay units, dual discharge paths, and unidirectional gated delay lines is provided. It is followed with the presentation of three time registered evolved from these time adders. Three time integrators developed from the preceding time adders and time registers are studied and their characteristics are compared. Finally, the design of a first-order ΔΣ time-to-digital converter utilising these arithmetic units is presented.
