An electrocardiogram (ECG) is used to record the electrical signal from the heart to check the functioning of heart conditions. The signals of ECG will be represented as waves on an attached monitor. Cardiovascular illnesses are identified using an electrocardiogram (ECG) signal processed using a Code Recombination Analog to Digital Converter (CR-ADC). The reduction in size of CMOS fabrication, delay rate, power consumption, noise and to increase the efficiency and accuracy of the ADC. This paper proposes the bidirectional pulsed-latches and non-overlap delayed pulsed clock signals which replace the existing master-slave flip-flops and 2-to-1 multiplexers to reduce the area and power consumption in ADC using code recombination algorithm. The CMOS fabrication of the ADC below 130 nm improves power efficiency. The prototype of CR-ADC implemented with a voltage source of 0.6 V, and a sampling rate of 10 kS/s, Signal-to-noise-distortion range (SNDR) and spurious-free dynamic range (SFDR) of the suggested ADC are 70.2 and 58.34 dB, respectively. It is more than 96% accurate compared to the Successive Approximation Register Analog to Digital Convertor (SAR-ADC).
