Patent number: 7816991Abstract: A controllable-gain circuit (TI, Rt, TS1, . . . , TS4) provides a first and a second pair of complementary gain-controlled signals (Ip1, Ip3; Ip2, Ip4) in response to an input signal (RFI). In each pair, one gain-controlled signal (Ip1, Ip2) is the input signal amplified with a gain G comprised in a range between a minimum gain Gmin and a maximum gain Gmax. The other gain-controlled signal (Ip3, Ip4) is the input signal amplified with complementary gain Gmax-G. A fixed-gain output circuit (Rfg, Nfg) makes a weighed sum (Ip1*Rfg+Ip3*Rfg) of one and the other gain-controlled signal in the first pair of complementary gain-controlled signals. The respective weighing factors for one and the other gain-controlled signal are substantially similar (Rfg). A controllable-gain output circuit (Rlg, Rhg, Nlg, Nhg) makes a weighed sum (Ip2*Rlg+Ip4*(Rlg+Rhg)) of one and the other gaincontrolled signal in the second pair of complementary gain-controlled signals.Type: GrantFiled: September 8, 2005Date of Patent: October 19, 2010Assignee: NXP B.V.Inventors: Thibault Philippe Paul Kervaon, Sebastien Amiot

Publication number: 20100260283Abstract: A duty-cycle modulated bit signalling method and circuit, comprising: signaling bits by virtue of a duty-cycle ratio; wherein the duty-cycle ratio is varied dependent upon the transmission rate of the signalling. A bit period comprises a long phase and a short phase and the duty-cycle therebetween is varied such that the ratio between the duration of the long phase and the duration of the short phase is increased for decreasing transmission rate. The duty-cycle ratio is varied dependent upon the transmission rate of the signalling according to one or more ranges of transmission rate. In a higher transmission rate range the duty-cycle is defined as a fixed ratio, and in a lower transmission range the duty-cycle is defined by a fixed length of the short phase of the bit period.Type: ApplicationFiled: November 12, 2008Publication date: October 14, 2010Applicant: NXP B.V.Inventor: Gerrit Willem Den Besten
