Abstract
An oscillator including an oscillator input node for receiving an oscillator input analog signal, an oscillator output node for providing a train of output pulses having a frequency related to the magnitude of the input analog signal, a trigger gate component connected between the input node and the output node and having a low threshold and a high threshold, the gate component being in a path between the input and output without other active components and having a low input current in the range of 1 uA or less, a feedback switch connected in parallel to the trigger gate component and having a switch turn on threshold such that the switch is turned on to conduct current when the trigger gate is in one output state and is turned off when the trigger gate is in the other output state, and capacitance between a reference voltage and the input node so that the voltage at the input node ramps from one threshold to the other at a rate dependent on the input current.
