ANALOGUE ELECTRONICS
Sensor Interface Electronics
We provide advanced solutions for designing high-sensitivity, low-noise analog sensor interface circuits, tailored for a wide range of applications. These include fluxgate magnetometers, accelerometers, gyroscopes, resolvers, piezoelectric sensors, and electrocardiograms, as well as other analog sensors and transducers.
Our designs incorporate drift and offset compensation, ensuring reliable, stable performance across both single-ended and differential amplifier configurations. By addressing noise reduction and signal accuracy, our sensor interfaces help maximize the performance of critical measurement and detection systems in industries like medical diagnostics, aerospace, automotive, and scientific research.
Analogue Front End
Our expertise in analog front-end circuit design ensures the highest level of signal processing performance, offering precision and adaptability for various applications. Key services include:
• Analog Filter Design: Development of both active and passive filters for precise signal filtering, conditioning, and channel compensation. These designs help in enhancing the quality and fidelity of signals by removing unwanted noise or interference, critical for achieving accurate measurements and data transmission.
• SPICE Simulation: We use industry-standard SPICE simulation tools, including LTSPICE, TINA, PSPICE, SIMetrix, and Simplis, to model and validate our designs. This allows us to simulate real-world operating conditions, ensuring that every aspect of the circuit functions as intended before physical prototyping.
• Diplexer Design: Specialized in high-voltage diplexer design for COP (Communications on Powerlines) data telemetry modems, facilitating reliable data transmission over power lines. This is particularly useful in energy distribution and smart grid applications, where combining data and power on the same infrastructure is vital for efficiency.
Power amplifier Design
Our power amplifier designs span various fields, focusing on both high-fidelity and high-efficiency solutions. We develop specialized power amplifiers to meet the unique demands of audio, positioning, and scientific applications:
• Audio Amplifiers: Expertise in designing Class-AB hi-fidelity amplifiers, known for their low distortion and smooth sound quality, alongside Class-D high-efficiency amplifiers, which offer excellent power conservation and reduced heat output, making them ideal for portable and high-power systems.
• Special Function Power Amplifiers: Custom-designed amplifiers for niche applications, including line drivers and magnetic or piezoelectric positioning systems. These amplifiers play a critical role in systems that require precise control of movement or force, used in fields like robotics, automation, and industrial machinery.
• High-Frequency Power Amplifiers: We design high-frequency power amplifiers for scientific applications such as electric or magnetic field generation, cancellation, or compensation. These amplifiers are essential in research areas like electromagnetic interference testing, medical imaging, and field calibration systems.
