Analog Elektronik Jobs

Please Note: total amount is $80. Please do not bid if this is not acceptable. I’m putting together a single-rail power supply for sensitive audio gear and need a clean, hum-free output. The brief is straightforward: • Topology: prefer an LDO-based regulator front-ended by a capacitance-multiplier stage (or an equally quiet alternative you can justify). • Input: board-mounted, fully encapsulated transformer—no off-board or open-frame types. • Output: 9 V to 24 V DC, up to 1.5 A continuous. Low ripple and broadband noise filtering are far more important than absolute efficiency. Include transformer snubbers. • Target use: high-end audio equipment, so 50/60 Hz mains-borne noise, switch-spikes and thermal drift must all be kept to a minimum. Deliverable...

I am building a board that needs a compact mixed-signal section dedicated to high-accuracy data conversion. The job is to design the entire ADC/DAC front-end, marrying the sensitive analog path with the supporting digital logic so the output is ready to drop straight onto my main PCB. What I need from you • A complete schematic showing the analog input stage, the chosen ADC and DAC devices, reference circuitry, clocking, and the glue logic that links everything to an MCU or FPGA header. • Component selection with justification, balancing performance, availability, and cost. • Simulations that verify noise, linearity, and timing (SPICE, LTspice, or similar). • A clean, well-annotated PCB layout file (Altium, KiCad, or Eagle—your choice, just tell me up fro...
