Respiratory infection is a major cause of exacerbation in chronic obstructive pulmonary disease (COPD). Infectious contributions to exacerbations remain incompletely described. We therefore analyzed respiratory tract samples by comprehensive real-time polymerase chain reaction (PCR) in combination with conventional methods. We evaluated multiple risk(More)
ditionally integrated are a newly designed voltage doubler-negative voltage generator (VDNVG) and a control logic circuit to control transmit and receive functions. The chip is capable of delivering 21-dBm output power at 39% efficiency with 2-V single power supply in transmit mode. By utilizing up-voltage and negative voltages generated from the generator,(More)
