My job is to design functional and tested circuits and PCBs for your application or consult you, so you can do that your self. Just give me requirements for your circuit: the price for bill of materials, deadline and a list of required features. After a prototype of the device is designed, which I almost always advise, I will order few sample PCBs for testing. After testing and debugging is completed, I will ship them to you, so you can verify my testing results. This costs extra for you, but you are buying 100% working circuit design which needs no testing. Just take it and use it in your project. If you want to know how a circuit works I can develop complete math model of the circuit. This approach is way more accurate than SPICE simulation and allows you to understand how the circuit operates. I have completed at least one project having fallowing sub circuits: Analog: Low noise, low speed front-ends (from Hz to 100KHz): Photodiode, strain gauge, pressure sensitive resistors, magnetic angle sensors, tensile, thermocouples and other. High order active filters Voltage measurement (uV to kV) Current measurement (pA to tens of A) Resistance measurements (mOhm to Mohm) Frequency measurement (below GHz) Current output Oscillators (Bubba, Pierce, Hartley, phase shift, relaxation, crystal, RC) Integrated RF transmitters/receivers Digital: PCIe USB HDMI I2S SPI High speed parallel interfaces Logic circuits (TTL, CMOS) SOCs Power: DC/DC converters: Buck, Boost, SEPIC, full bridge, Cuk, Linear AC/DC converters (up to 1.8kW) Brushless and brushed motor drivers TEC drivers CAD packages: DipTrace KiCad Altium I have fallowing equipment: 1x Osciloscope RTB2004 4 channel 10 bit 300MHz with logic analyzer having 16 differential channels up to 600Mbps. 1x Oscilloscope HMO1002 2 channel 8 bit 50MHz. 1x Multimeter HMC8012 5,75digit 1x Electronic load IT8616 1.8kVA 420VAC 20AC (60A peak) or 600VDC 20ADC with AC signal analysis 1x Electronic load IT8512C 120VDC 60ADC 1x Signal generator Rohde and Schwarz AFG 20MHz 1x TP3020 30V 20A linear power supply 1x HY5003-2 dual channel 50V 3A linear power supply 2x PeakTech 6080A 15V 3A power supply 1x VP-2000VA - 2kVA 230VAC to 120VAC converter. 1x DER-EE DE-5000 RLC meter I also have programmer for: Texas Instruments CC series, Texas Instruments MSP430 programmer, Microchip ICD3/PicKit2/AVR ISP USBasp, Segger ARM programmer, SiliconLabs 8051 core programmer
