This paper highlights some of the challenges associated with the current paper-based immunization health card being used in the Punjab province of Pakistan, and further discusses an iterative approach to redesign this card to be more informative for parents in general with a special focus on a low-literate audience. The discussion builds upon user(More)
Design of a digital dynamic divider in SiGe bipolar technology is presented in this paper. The proposed digital dynamic frequency divider is based on two latches connected with negative feedback. However, in contrast to the conventional static frequency divider the latching differential pair has been completely omitted to reduce the load for the sensing(More)
Routine early age child immunization is one of the most cost-effective public health interventions. The use of Information and Communication Technology (ICT) tools such as Immunization Information Systems (IIS) to improve efficiency of vaccination programs has shown mixed but encouraging results in terms of success. The objective of this paper is to present(More)
In this paper, the design and characterization of fundamental voltage controlled oscillators (VCOs) operating in the range from 138 to 146 GHz (VCO-I) and 150.8 to 158.3 GHz (VCO-II) are presented. Both VCO-I and Π are based on Colpitts topology. Additionally, a frequency divider chain (with a divide ratio 8) is added in front of the VCO-I for the(More)
