Abstract

Abstract: This paper presents a novel switched capacitor biquad with a high gain differential amplifier for the first time using amorphous indium‐gallium‐zinc‐oxide thin‐film transistors on flexible (polyimide) substrate. The proposed low‐pass filter was successfully characterised under normal ambient conditions. The circuit has shown a 3‐dB cutoff frequency of 155 Hz and power consumption of 336 μW from measurements with a power supply voltage of 10 V. This circuit would find potential applications in wearable continuous health monitoring systems.
