Summary
This study introduces a novel current-controlled oscillator (CCO) for mixed-mode instrumentation. The CCO operates at low voltage with minimal power and ground bounce, offering high linearity and stable performance.
Area of Science:
- Electrical Engineering
- Analog Integrated Circuit Design
Background:
- Mixed-mode instrumentation systems require low-noise, stable components.
- Traditional current-controlled oscillators (CCOs) can suffer from power supply sensitivity and noise.
Purpose of the Study:
- To design and propose a low-sensitivity, low-bounce, high-linearity CCO.
- To demonstrate its suitability for single-supply mixed-mode instrumentation systems.
Main Methods:
- Design of a novel current-controlled oscillator (CCO).
- Low-voltage (2 V) operation.
- Evaluation of power bounce, ground bounce, and power supply noise under parasitic inductance.
Main Results:
- Achieved low power bounce (<7 mVpp) and ground bounce.
- Minimal power supply noise (<0.35% of 2 V supply).
- High conversion linearity (within +/-1.2%) with an average ratio (KCCO) of 123.5 GHz/A.
Conclusions:
- The proposed CCO exhibits superior performance compared to conventional current-starved oscillators.
- Its low sensitivity and high linearity make it ideal for single-supply mixed-mode instrumentation.

01:25Instrumentation Amplifier
An electrocardiography (ECG) machine is an essential piece of medical equipment used to monitor the electrical activity of the heart. It operates by detecting small electrical changes on the skin that result from the depolarization of the heart muscle during each heartbeat. However, these signals are in the microvolt range and can be easily overwhelmed by noise or interference.

01:30Oscillations In An LC Circuit
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

The operational amplifier, often referred to as an op-amp, is a multifaceted building block of a circuit. This electronic component functions like a voltage-controlled voltage source and can also be used to create a voltage- or current-controlled current source. The design of an operational amplifier enables it to execute mathematical operations when external components like resistors and capacitors are linked to its terminals. An op-amp has the capacity to sum signals, amplify a signal,...

In an inverting amplifier, the input voltage is connected through a resistor to the inverting terminal. Meanwhile, the non-inverting terminal is grounded and a feedback resistor is established between the inverting and output terminal, as depicted in Figure 1.
01:16Cascaded Op Amps
Operational amplifiers (op-amps) are versatile electronic components that can be interconnected in a cascade - one after another in a linear sequence. This cascading is possible due to their infinite input resistance and zero output resistance, allowing them to maintain their input-output relationships even when connected in series.
In a cascaded system, each op-amp is referred to as a stage. The output of one stage drives the input of the subsequent stage. As the input signal passes through...

01:27Controlled-Current Coulometry: Overview
Controlled current coulometry, also known as amperostatic coulometry, is a technique used in electrochemical analysis to measure the quantity of a substance through the controlled passage of current. It involves the application of a constant current to an electrochemical cell containing the analyte of interest. As the current flows through the cell, the analyte undergoes a redox reaction at the electrode surface, resulting in a charge transfer. By monitoring the time required for a certain...
