SPECS Frequency Range = 130.81 Hz 1046.5 Hz Control Relation = 1V/Octave
Choosing the Best Waveform Increasing Frequency Content
VCO Design EC
Voltage-Controlled Filter Bandwidth Equation: Operational Transconductance Amplifier (OTA) OTA Transfer Characteristic Equation:
VCF Performance Bandwidth-Current Relation VCF Output Bode Plot Input Current: 500pA Input Signal: 1mV (-60 dB)
Our Amazingly Simple Mixer. The Final Output: Filtered Signal mixed with the AR Wave Gain Control Stage Small Signal Amplification Stage
Improvements(for the next design cycle) • Higher frequency range VCO • Use higher order filters (instead of single pole) • ADSR • More effective mixer • Independent biasing circuits
