“…The ultimate purpose of differential amplifier circuit is to amplify the differential mode signal and suppress the common mode signal. Compared with single-ended amplifier circuit, differential amplifier circuit has stronger anti-interference ability and can effectively suppress zero drift and common-mode signal [2].…”

Wearable electrocardiogram (ECG) sensors is a simple test that can be used to check people’s heart's rhythm and electrical activity. With individuals’ increasing attention to their own health, developing a timely and portable bio-sensing recorder has become an urgent task. This paper presents the working principle of a common ECG signal recorder. A double-electrode voltage amplifier that can be used for portable ECG sensors has been set out to design. The amplifier is mainly composed of a differential amplifier circuit, which can lower power supply and power consumption. CoolSpice environment was utilized to simulate the circuit and analyze the result. The simulation presented that the common-mode gain is under 30dB up to 5KHz and the differential-mode gain is larger than 40 dB up to 5KHz. And the total current consumption has been under 20uA. The result demonstrated that the amplifier can perform well. The noise from human body has been eliminated by the amplifier. The amplifier has the ability to extract and amplify clean ECG signals and its structure has the characteristics of low cost and portability. It may be used in portable wearable ECG sensor technology.

“…The Pass transistor (pass element) works in the linear region to reduce the incoming supply voltage down to the required output voltage and also supplies the incoming current to the load. Error amplifier (EA) sense the resulting output voltage and compares it with the reference voltage given by the reference voltage source, here the BGR (Band-gap Reference circuit) is the reference voltage source, and the BGR circuit is used whenever temperature independent reference voltage is required [5]…”

Low Dropout (LDO) Voltage Regulators are the linear regulators which drives upon a very small differential voltage. The main components of the Low dropout voltage regulators are Error amplifier, Pass device, voltage reference source and Voltage divider network. The low dropout voltage regulator uses a variable input to give a steady, constantly controlled, low-noise DC output voltage. This is a linear voltage regulator that includes a small voltage drop among the input as well as the output that works even when the output voltage is extremely close to the input voltage. The Error amplifier circuit which is one of the components in Low dropout voltage regulator is designed in the standard 180nm CMOS technology, with supply voltage of 1.6V, the gain of the error amplifier is 74db, Band-gap reference circuit is implemented to produce stable reference voltage which is independent of temperature variations. The bandgap reference voltage circuit gives the output voltage of 1.2V. The low dropout voltage regulator produces constant output voltage of 1.8V for the input voltage range 2.1V to 3.5V and it provides constant output voltage for load variations.

“…Although this report demonstrates a small core area of 0.52 mm 2 , the multi-port inductors need to iterate electromagnetic analysis for design optimization. On the other hand, cascaded amplifiers realize high gain-bandwidth product with a small area [13][14]. However, increasing the number of cascaded stages leads to increased power consumption and weakness of process, voltage, and temperature (PVT) variation.…”

This paper presents an area-efficient differential distributed amplifier using differential coupled inductors. The artificial transmission lines of the proposed distributed amplifier are modeled as differential transmission lines, and thus, it can be easily designed compared with other area reduction techniques. The dimensions of the coupled inductors have been optimized using a gradient descent algorithm with a scalable model of the coupled inductors. The proposed amplifier was designed using 1P5M 180 nm standard CMOS technology. Post-layout simulation results demonstrated a gain of 6.9 dB and a bandwidth of 20.2 GHz with 4.9 ps Nyquist group delay variation. A core area of the proposed amplifier was 0.28 , which was the smallest value compared with previous works using similar processes.
