Corporate Political Ideology and Environmental Strategy: Evidence From US Toxic Releases
Business Strategy and the Environment, EarlyView.ABSTRACT This paper examines whether corporate political ideology shapes firms' environmental strategy and realized environmental performance. Using US political donation data matched to facility‐level toxic releases from the Toxics Release Inventory from 2000 to 2014, we measure corporate ideology by the share of firm and PAC contributions directed to

Impact of Bias Schemes on Doherty Power Amplifiers [PDF]
2005 IEEE International Symposium on Circuits and Systems, 2005 This paper investigates the performance of a 2.4GHz CMOS two-way Doherty power amplifier with the different bias schemes for the auxiliary power device. For the conventional bias schemes, there are design tradeoffs in terms of power gain, gain flatness, P/sub 1dB/, power-added efficiency, and third order harmonics.
