Although tuberculosis has become more common in recent years, it still accounts for just a small percentage of cases of chronic otitis media. Common symptoms of tuberculous otitis media(TOM) include otorrhoea, hearing loss, and multiple tympanic membrane perforations. Due to its rarity, the illness is frequently misdiagnosed. When a patient does not improve with standard antibacterial and antifungal treatment, this may be a possible diagnosis to explore. Complete healing is possible if the illness is diagnosed and treated timely to prevent consequences.

A high dynamic range and low-noise CMOS(complementary metal-oxide-semiconductor transistor)front-end interface integrated circuit(IC) with multi-channel detection is presented in this paper. Two different current detection channels, composed of a trans-impedance amplifier(TIA) and an integrator-differentiator TIA, are used to boost the current detection range. A capacitance-coupled instrument amplifier(CCIA) is also included to realize high precision voltage detection. A fourth-order sigma-delta modulator using a second-order loop filter and a second-order noise shaping integral quantizer is adopted to realize effective number of bits above 16 bits. The presented interface IC is implemented in 0.18-μm CMOS process with supply voltage of 3.3 V, and a proto-type electrochemical sensor platform with miniaturized sensor array is developed to verify the functionality of the interface IC. Measurement results indicate that the designed interface IC achieves 157.8 d B current detection dynamic range, and the measured input-referred current noise and voltage noise floor are 1.04 p A and 58.4 n V within 10 k Hz integration bandwidths,respectively.
