    • A quadrature output (IP, IN, QP, QN) high-frequency RF divide-by-two circuit (129) includes a pair of differential complementary logic latches (142, 143). The latches are interconnected to form a toggle flip-flop (200). Each latch (200) includes a tracking cell and a locking cell. In a first embodiment (200), the locking cell includes two complementary logic inverters (201, 205, 203, 207) and two transmission gates (202, 206; 204, 208). When the locking cell is locked, the two gates (211, 213; 212, 214) are enabled such that the locked (i.e., latched) signal passes through both transmission gates and both inverters. In one advantageous aspect, the tracking cell only involves two transmission gates (211, 213; 212, 214). Due to the circuit topology, the first embodiment is operable from a low supply voltage at a high operating frequency while consuming a low amount of supply current. In a second (300) and third embodiment (400), the tracking cell involves a pair of inverters ((301, 304; 302, 305) or (401, 404; 402, 405)). The sources of the transistors of the inverters are, however, coupled together thereby resulting in performance advantages over conventional circuits.
    • 正交输出(IP,IN,QP,QN)高频RF分频电路(129)包括一对差分互补逻辑锁存器(142,143)。 锁存器互连以形成切换触发器(200)。 每个锁存器(200)包括跟踪单元和锁定单元。 在第一实施例(200)中,锁定单元包括两个互补逻辑反相器(201,205,203,207)和两个传输门(202,206; 204,208)。 当锁定单元被锁定时,两个门(211,213,212,214)被使能使得锁定(即锁存的)信号通过两个传输门和两个逆变器。 在一个有利的方面,跟踪单元仅涉及两个传输门(211,213; 212,214)。 由于电路拓扑结构,第一实施例可以在高工作频率的低电源电压下工作,同时消耗低的电源电流。 在第二(300)和第三实施例(400)中,跟踪单元涉及一对逆变器((301,304,302,305)或(401,404; 402,405))。 然而,逆变器的晶体管的源极耦合在一起,从而导致相对于常规电路的性能优点。

    • [A high-speed low-power latch includes three sets of transistors. A first set of transistors selects a tracking mode or a holding mode for the latch based on a clock signal having non-rail-to-rail or rail-to-rail voltage swing. A second set of transistors captures a data value based on an input signal and provides an output signal during the tracking mode. A third set of transistors stores the data value and provides the output signal during the holding mode. The input and output signals have rail-to-rail voltage swing. In another aspect, a signal generator includes at least one latch and a control circuit. The latch(es) receive a clock signal and generate an output signal. The control circuit senses a duty cycle of a feedback signal derived from the output signal and generates a control signal to adjust operation of the latch(es) to obtain 50% duty cycle for the feedback signal.
