Description of Compartor IC Essentially a very fast-acting high-gain differential amplifier, a comparator senses the difference between two voltages and, by rapid amplification, provides maximum output immediately. Its output is a large voltage which is assumed to represent a digital 1 or 0 level. They are made of AND, NOT & NOR Gates. The large voltage variations in the internal nodes are coupled to the input, disturbing the input voltage-this is usually called kickback noise. To make a difference, we give different colors to the pins of each comparator. �,dM8PD�G`.�O�q�V"�1R͔� �^�o�;t�kc��i�,#B��ַ����P�n��E�K�-�i�g�3a� 6���"�=����y�1��j�SJ�`�57�{����d�j�4Q��p���dqo�XV���3�+o�#)�B"����8&}������9���?

De-signed for low-input current, most comparators are essentially voltage devices that interface with digital logic circuits. Also operation from dual supplies is possible, as long as the difference between the two supplies is 2 V to 36 V. A new high-performance CMOS current comparator is proposed. A comparator rotates a signal between digital and analog domain. The comparator 10 may be implemented with three hex inverter IC packages, such as RCA's CD4069B, with two gates or transistors being required per inverter, … where y is the output signal, 0 D represents the logic zero and 1 D is the logic one. Ideal comparators should be capable to detect arbitrarily small differences between the input signals. However, in practice, these differences must be larger than a characteristic resolution parameter ξ for proper detection. A comparator is the basic component mainly used in analog-to-digital converters. ¾ The gain can be obtained in multiple stages.
