Title:
COUNTER CIRCUIT, MEASURING DEVICE, AND PHYSICAL QUANTITY SENSOR
Document Type and Number:
Japanese Patent JP2018160817
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a counter circuit, a measuring device, and a physical quantity sensor, capable of reducing a through current when a carry-over occurs and which can make the circuit configuration simple and small scale.SOLUTION: The counter circuit includes a counter unit having m (m is an integer of 2 or more) bit counters having n (n is an integer of 2 or more) steps. At least one of the n-step-m-bit counters outputs a carry-over signal at a transition time when a Hamming distance between a state before the transition and a state after the transition is other than m.SELECTED DRAWING: Figure 1
