Class-D amplifier power stage with PWM feedback loop
This paper presents a second-order pulsewidth modulation (PWM) feedback loop to improve power supply rejection (PSR) of any open-loop PWM class-D amplifiers (CDAs). PSR of the audio amplifier has always been a key parameter ...
A 9.87 nW 1 kS/s 8.7 ENOB SAR ADC for implantable epileptic seizure detection microsystems
This paper presents an ultra low-power SAR ADC in 0.18 μm CMOS technology for epileptic seizure detection applications. The ADC is powered by a single supply voltage of both analog and digital circuits to avoid using the ...
