Gated Ring Oscillator Time Amplifier with Applications in Time Integration

A new gated ring oscillator time amplifier (GRO-TA) featuring a well-defined linear programmable gain, a virtually unlimited range of gain, the ability to amplify a sub-pico-second time input, fast amplification, low power consumption, and full compatibility with technology is proposed. The time amplifier is utilized in development of an all-digital time integrator. Both the time amplifier and time integrator are designed in a TSMC 130 nm 1.2 V CMOS technology and analyzed using Spectre with BSIM3 device models. Simulation results are presented.
