Technologies in Electronics Design UK

electronic design technologiesAnalogue
In a world of increasing application notes and application-specific integrated circuits, pure analogue design is in short supply in many companies. At MLE we have a good depth of analogue and audio-to-video electronic design expertise. Devices typically being discrete analogue; amplifiers being high common mode low noise, high impedance, charge amplifiers. Other configurations of integrators, differentiators, gyrators and the like. Added to this is a broad experience of layout and wiring techniques.

Embedded Intelligence
Over the years we have used many embedded processors of 8 bit, 16 bit or 32 and 64 bit designs; typical devices may be PIC, ARM7, ARM9, Intel or Texas Instruments' devices.
Typical DSP processors are the Texas Instruments' TMS320F24 and the Arizona Micropchip dsPIC.
We recently contracted with Cypress to be the lead design house in the UK and Ireland for the exciting embedded PSOC devices covering Capsense, TrueTouch, Firsttouch and EZ Colour.

Software
We provide software design for PC's in Visual Basic, C (+/++) and JavaScript. Applications for the PC are numerous but could typically be: calibration, custom equipment control, interactive test environments, launch pads for applications, databases, communication systems etc. We also design using PERL and JAVA for integrated internet gateway applications. In designing hardware, we programme at machine-code level, using assembly language if speed or code efficiency is required. By fully understanding the client's requirements and by having control of both software and hardware, we offer a solution that is optimised for the scale of the production.

Power Supply and Motor Drives
Power supplies are great technology to design as they embrace so many of the disciplines, especially in these days of DSP controlled units with complex control algorithms and even spread spectrum EMC noise reduction. DSPs now have multiple micro precision PWM outputs for advanced control of many topologies of controller, whether it be 3phase inverters, quasi resonant phase shifted half bridge designs or simple chopper, forward or flyback topologies. Devices range from mW transistors through KW switching modules of FET or IGBT devices. Power technology is key to many electronic design projects and we have designed PSUs for many years and welcome your challenging requirements.

Control Theory, Mathematics and DSP Algorithms.
As DSPs become more powerful, yet low power and cost effective, it is realistic to achieve more within a small DSP device. We have a wide experience of integrating, differentiating, PID, PI loops and fuzzy logic style control loops. With experience of MATLAB and finite element UK electronics designanalysis, we can create specialist routines for most applications. Recent projects in noise cancellation and wavelet decimation required complex analysis and critical timing.
