--In this paper, the design of low noise, power efficient Biosensing amplifier and analog to digital converter (ADC) for wireless body sensor nodes and medical implantable gadgets. These design parameters helps to thorough analysis of biomedical recording systems and optimize them. Based on the analysis of biosensing amplifier, the design methodology is applicable for various biomedical applications. The design is done in 45nm Technology. The input signal which is taken for the design is mixed with noise and also the gain of the signal is very poor. In order to decrease the noise and increase the gain of the signal this design is implemented. For that reason, the chip is incorporated with Low clamor Amplifier (LCA), third order Gm-C Low Pass Filter (LPF) and 10-bit Successive Approximation Register (SAR) Analog to Digital Converter. The AFE gain is >100 dB. The AFE and ADC utilize only 133nW and 306nW from on chip regulators, respectively. The measured input referred noise is 0.387pVrms.

Analog front end (AFE), low clamor amplifier (LCA), implantable gadgets, wireless body sensor nodes (WBSN), power efficient.
