Analog/Mixed-Signal Designer of ADC IPs (from Mar. '19)Examples of projects:- Quantizer, amplifiers, and high-speed digital for cellular receive path ADCs- Low-power and high-speed SAR ADCs for WiFi receive pathAnalog/Mixed-Signal Designer of Audio CODEC SOCs (Feb. '14 - Feb. '19)Examples of projects, many of which are selling in premium and high tier phones:- Lead for audio record path circuit improvements- System and DSP design for audio playback path and ANC- Circuit speed monitoring system for voice activation DSP power reduction- Battery monitoring ADC for playback power adjustmentThe success of these circuit systems involves significant collaboration with other functional groups, such as system design, digital/physical design, process development, etc.
