A feed-forward noise cancellation (FFNC) technique to improve the power supply noise rejection (PSR) of a low dropout regulator (LDO) is presented. The proposed FFNC operates in conjunction with a conventional LDO and extends the noise rejection bandwidth by nearly an order of magnitude. Fabricated in 0.18µm CMOS, at 10mA load current, the prototype(More)
Though there has been widespread enthusiasm to leverage technology to strengthen low-resource classrooms, to date very few programs have documented rigorous benefits from such interventions. In this paper, we describe an exploratory evaluation of the use of pre-packaged electronic teaching aids, consisting of presentation slides and multimedia content, in a(More)
