An Analog Voltage Similarity Circuit with a Bell-Shaped Power Consumption

This paper presents a voltage similarity circuit (bump circuit) based on novel correlator. The proposed is characterized by power consumption which depends the between two inputs. sensitivity of bump and are at highest values when inputs equal. As input voltages decreases, total current decreases with bell-shaped behavior. very simple in design, made new correlator combination differential pair mimics behavior classical circuit. was implemented using AMS−350nm CMOS technology. Simulation measurement results suggests that low may be achieved if used applications where signals have large dissimilarity for most operation.
