Abstract: Systems, apparatuses, and methods for an on chip dynamic IR oscilloscope are provided. An oscilloscope circuitry may comprise sensor circuitry, voltage generator circuitry, finite state machine, and latch circuitry. The sensor circuitry may include digital logic circuitry, sample and hold circuitry, and sense amplifier circuitry. The voltage generator circuitry may include a voltage generator, analog buffers, switches, and high speed buffer. The finite state machine may control the sensor circuitry to sample a voltage waveform and the voltage generator circuitry to generate a reference voltage that may change over time. The sensing amplifier circuitry may compare the samples to the reference voltage to generate flags when a sample exceeds a reference voltage. The flags may be used to stored the voltages associated with the flags, which may be used to redraw the waveform sampled.
